From 93d9dde969a9bc3983b4bcb656970453730ae3eb Mon Sep 17 00:00:00 2001 From: Robin Sommer Date: Tue, 10 Dec 2013 16:26:34 -0800 Subject: [PATCH 01/85] IOSource reorg. A bunch of infrastructure work to move IOSource, IOSourceRegistry (now iosource::Manager) and PktSrc/PktDumper code into iosource/, and over to a plugin structure. Other IOSources aren't touched yet, they are still in src/*. It compiles and does something with a small trace, but that's all I've tested so far. There are quite certainly a number of problems left, as well as various TODOs and cleanup; and nothing's cast in stone yet. Will continue to work on this. --- TODO.iosources | 9 + aux/broccoli | 2 +- aux/broctl | 2 +- src/CMakeLists.txt | 7 +- src/DNS_Mgr.cc | 13 +- src/DNS_Mgr.h | 6 +- src/DebugLogger.cc | 3 +- src/DebugLogger.h | 1 + src/FlowSrc.cc | 15 +- src/FlowSrc.h | 4 +- src/Net.cc | 119 +-- src/Net.h | 22 +- src/PacketSort.cc | 2 +- src/PacketSort.h | 8 +- src/PktSrc.cc | 796 ------------------ src/PktSrc.h | 258 ------ src/RemoteSerializer.cc | 34 +- src/RemoteSerializer.h | 4 +- src/Serializer.cc | 19 +- src/Serializer.h | 4 +- src/Sessions.cc | 24 +- src/Sessions.h | 4 +- src/bro.bif | 73 +- src/iosource/CMakeLists.txt | 23 + src/iosource/Component.cc | 44 + src/iosource/Component.h | 56 ++ src/{ => iosource}/IOSource.h | 76 +- src/{IOSource.cc => iosource/Manager.cc} | 151 +++- src/iosource/Manager.h | 75 ++ src/iosource/pktsrc/CMakeLists.txt | 2 + src/iosource/pktsrc/Component.cc | 130 +++ src/iosource/pktsrc/Component.h | 132 +++ src/iosource/pktsrc/PktDumper.cc | 79 ++ src/iosource/pktsrc/PktDumper.h | 57 ++ src/iosource/pktsrc/PktSrc.cc | 411 +++++++++ src/iosource/pktsrc/PktSrc.h | 140 +++ src/iosource/pktsrc/old-2ndary-code.h | 69 ++ src/{ => iosource/pktsrc/pcap}/BPF_Program.cc | 0 src/{ => iosource/pktsrc/pcap}/BPF_Program.h | 0 src/iosource/pktsrc/pcap/CMakeLists.txt | 8 + src/iosource/pktsrc/pcap/Dumper.cc | 111 +++ src/iosource/pktsrc/pcap/Dumper.h | 40 + src/iosource/pktsrc/pcap/Plugin.cc | 12 + src/iosource/pktsrc/pcap/Source.cc | 343 ++++++++ src/iosource/pktsrc/pcap/Source.h | 60 ++ src/main.cc | 16 +- src/plugin/Component.cc | 12 + src/plugin/Component.h | 7 +- src/plugin/Macros.h | 27 + src/threading/Manager.cc | 8 +- src/threading/Manager.h | 4 +- src/util.cc | 7 +- 52 files changed, 2223 insertions(+), 1306 deletions(-) create mode 100644 TODO.iosources delete mode 100644 src/PktSrc.cc delete mode 100644 src/PktSrc.h create mode 100644 src/iosource/CMakeLists.txt create mode 100644 src/iosource/Component.cc create mode 100644 src/iosource/Component.h rename src/{ => iosource}/IOSource.h (51%) rename src/{IOSource.cc => iosource/Manager.cc} (52%) create mode 100644 src/iosource/Manager.h create mode 100644 src/iosource/pktsrc/CMakeLists.txt create mode 100644 src/iosource/pktsrc/Component.cc create mode 100644 src/iosource/pktsrc/Component.h create mode 100644 src/iosource/pktsrc/PktDumper.cc create mode 100644 src/iosource/pktsrc/PktDumper.h create mode 100644 src/iosource/pktsrc/PktSrc.cc create mode 100644 src/iosource/pktsrc/PktSrc.h create mode 100644 src/iosource/pktsrc/old-2ndary-code.h rename src/{ => iosource/pktsrc/pcap}/BPF_Program.cc (100%) rename src/{ => iosource/pktsrc/pcap}/BPF_Program.h (100%) create mode 100644 src/iosource/pktsrc/pcap/CMakeLists.txt create mode 100644 src/iosource/pktsrc/pcap/Dumper.cc create mode 100644 src/iosource/pktsrc/pcap/Dumper.h create mode 100644 src/iosource/pktsrc/pcap/Plugin.cc create mode 100644 src/iosource/pktsrc/pcap/Source.cc create mode 100644 src/iosource/pktsrc/pcap/Source.h diff --git a/TODO.iosources b/TODO.iosources new file mode 100644 index 0000000000..7380c89b92 --- /dev/null +++ b/TODO.iosources @@ -0,0 +1,9 @@ +- Move the current_{iosrc,pkt_src,etc.} into manager +- Remove all 2ndary path code +- Remove all flow src code. +- Move pktsrc/*.{h,cc} up a level?

This + affects the scope of any subsequently declared global identifiers. + + Example:: + + module mymodule; + + If a global identifier is declared after a "module" declaration, + then its scope ends at the end of the current Bro script or at the + next "module" declaration, whichever comes first. However, if a + global identifier is declared after a "module" declaration, but inside + an :bro:keyword:`export` block, then its scope ends at the end of the + last loaded Bro script, but it must be referenced using the namespace + operator (``::``) in other modules. + + There can be any number of "module" declarations in a Bro script. + The same "module" declaration can appear in any number of different + Bro scripts. + + +.. bro:keyword:: export + + An "export" block contains one or more declarations + (no statements are allowed in an "export" block) that the current + module is exporting. This enables these global identifiers to be visible + in other modules (but not prior to their declaration) via the namespace + operator (``::``). See the :bro:keyword:`module` keyword for a more + detailed explanation. + + Example:: + + export { + redef enum Log::ID += { LOG }; + + type Info: record { + ts: time &log; + uid: string &log; + }; + + const conntime = 30sec &redef; + } + + Note that the braces in an "export" block are always required + (they do not indicate a compound statement). Also, no semicolon is + needed to terminate an "export" block. + +.. bro:keyword:: global + + Variables declared with the "global" keyword will be global. + If a type is not specified, then an initializer is required so that + the type can be inferred. Likewise, if an initializer is not supplied, + then the type must be specified. Example:: + + global pi = 3.14; + global hosts: set[addr]; + global ciphers: table[string] of string = table(); + + Variable declarations outside of any function, hook, or event handler are + required to use this keyword (unless they are declared with the + :bro:keyword:`const` keyword). Definitions of functions, hooks, and + event handlers are not allowed to use the "global" + keyword (they already have global scope), except function declarations + where no function body is supplied use the "global" keyword. + + The scope of a global variable begins where the declaration is located, + and extends through all remaining Bro scripts that are loaded (however, + see the :bro:keyword:`module` keyword for an explanation of how modules + change the visibility of global identifiers). + + +.. bro:keyword:: const + + A variable declared with the "const" keyword will be constant. + Variables declared as constant are required to be initialized at the + time of declaration. Example:: + + const pi = 3.14; + const ssh_port: port = 22/tcp; + + The value of a constant cannot be changed later (the only + exception is if the variable is global and has the :bro:attr:`&redef` + attribute, then its value can be changed only with a :bro:keyword:`redef`). + + The scope of a constant is local if the declaration is in a + function, hook, or event handler, and global otherwise. + Note that the "const" keyword cannot be used with either the "local" + or "global" keywords (i.e., "const" replaces "local" and "global"). + + +.. bro:keyword:: type + + The "type" keyword is used to declare a user-defined type. The name + of this new type has global scope and can be used anywhere a built-in + type name can occur. + + The "type" keyword is most commonly used when defining a + :bro:type:`record` or an :bro:type:`enum`, but is also useful when + dealing with more complex types. + + Example:: + + type mytype: table[count] of table[addr, port] of string; + global myvar: mytype; + +.. bro:keyword:: redef + + There are three ways that "redef" can be used: to change the value of + a global variable, to extend a record type or enum type, or to specify + a new event handler body that replaces all those that were previously + defined. + + If you're using "redef" to change a global variable (defined using either + :bro:keyword:`const` or :bro:keyword:`global`), then the variable that you + want to change must have the :bro:attr:`&redef` attribute. If the variable + you're changing is a table, set, or pattern, you can use ``+=`` to add + new elements, or you can use ``=`` to specify a new value (all previous + contents of the object are removed). If the variable you're changing is a + set or table, then you can use the ``-=`` operator to remove the + specified elements (nothing happens for specified elements that don't + exist). If the variable you are changing is not a table, set, or pattern, + then you must use the ``=`` operator. + + Examples:: + + redef pi = 3.14; + + If you're using "redef" to extend a record or enum, then you must + use the ``+=`` assignment operator. + For an enum, you can add more enumeration constants, and for a record + you can add more record fields (however, each record field in the "redef" + must have either the :bro:attr:`&optional` or :bro:attr:`&default` + attribute). + + Examples:: + + redef enum color += { Blue, Red }; + redef record MyRecord += { n2:int &optional; s2:string &optional; }; + + If you're using "redef" to specify a new event handler body that + replaces all those that were previously defined (i.e., any subsequently + defined event handler body will not be affected by this "redef"), then + the syntax is the same as a regular event handler definition except for + the presence of the "redef" keyword. + + Example:: + + redef event myevent(s:string) { print "Redefined", s; } + + +.. _function/event/hook: + +**function/event/hook** + For details on how to declare a :bro:type:`function`, + :bro:type:`event` handler, or :bro:type:`hook`, + see the documentation for those types. + + +Statements +---------- + +Each statement in a Bro script must be terminated with a semicolon (with a +few exceptions noted below). An individual statement can span multiple +lines. + +All statements (except those contained within a function, hook, or event +handler) must appear after all global declarations. + +Here are the statements that the Bro scripting language supports. + +.. bro:keyword:: add + + The "add" statement is used to add an element to a :bro:type:`set`. + Nothing happens if the specified element already exists in the set. + + Example:: + + local myset: set[string]; + add myset["test"]; + +.. bro:keyword:: break + + The "break" statement is used to break out of a :bro:keyword:`switch` or + :bro:keyword:`for` statement. + + +.. bro:keyword:: delete + + The "delete" statement is used to remove an element from a + :bro:type:`set` or :bro:type:`table`. Nothing happens if the + specified element does not exist in the set or table. + + Example:: + + local myset = set("this", "test"); + local mytable = table(["key1"] = 80/tcp, ["key2"] = 53/udp); + delete myset["test"]; + delete mytable["key1"]; + +.. bro:keyword:: event + + The "event" statement immediately queues invocation of an event handler. + + Example:: + + event myevent("test", 5); + +.. bro:keyword:: fallthrough + + The "fallthrough" statement can be used as the last statement in a + "case" block to indicate that execution should continue into the + next "case" or "default" label. + + For an example, see the :bro:keyword:`switch` statement. + +.. bro:keyword:: for + + A "for" loop iterates over each element in a string, set, vector, or + table and executes a statement for each iteration. + + For each iteration of the loop, a loop variable will be assigned to an + element if the expression evaluates to a string or set, or an index if + the expression evaluates to a vector or table. Then the statement + is executed. However, the statement will not be executed if the expression + evaluates to an object with no elements. + + If the expression is a table or a set with more than one index, then the + loop variable must be specified as a comma-separated list of different + loop variables (one for each index), enclosed in brackets. + + A :bro:keyword:`break` statement can be used at any time to immediately + terminate the "for" loop, and a :bro:keyword:`next` statement can be + used to skip to the next loop iteration. + + Note that the loop variable in a "for" statement is not allowed to be + a global variable, and it does not need to be declared prior to the "for" + statement. The type will be inferred from the elements of the + expression. + + Example:: + + local myset = set(80/tcp, 81/tcp); + local mytable = table([10.0.0.1, 80/tcp]="s1", [10.0.0.2, 81/tcp]="s2"); + + for (p in myset) + print p; + + for ([i,j] in mytable) { + if (mytable[i,j] == "done") + break; + if (mytable[i,j] == "skip") + next; + print i,j; + } + + +.. bro:keyword:: if + + Evaluates a given expression, which must yield a :bro:type:`bool` value. + If true, then a specified statement is executed. If false, then + the statement is not executed. Example:: + + if ( x == 2 ) print "x is 2"; + + + However, if the expression evaluates to false and if an "else" is + provided, then the statement following the "else" is executed. Example:: + + if ( x == 2 ) + print "x is 2"; + else + print "x is not 2"; + +.. bro:keyword:: local + + A variable declared with the "local" keyword will be local. If a type + is not specified, then an initializer is required so that the type can + be inferred. Likewise, if an initializer is not supplied, then the + type must be specified. + + Examples:: + + local x1 = 5.7; + local x2: double; + local x3: double = 5.7; + + Variable declarations inside a function, hook, or event handler are + required to use this keyword (the only two exceptions are variables + declared with :bro:keyword:`const`, and variables implicitly declared in a + :bro:keyword:`for` statement). + + The scope of a local variable starts at the location where it is declared + and persists to the end of the function, hook, + or event handler in which it is declared (this is true even if the + local variable was declared within a `compound statement`_ or is the loop + variable in a "for" statement). + + +.. bro:keyword:: next + + The "next" statement can only appear within a :bro:keyword:`for` loop. + It causes execution to skip to the next iteration. + + For an example, see the :bro:keyword:`for` statement. + +.. bro:keyword:: print + + The "print" statement takes a comma-separated list of one or more + expressions. Each expression in the list is evaluated and then converted + to a string. Then each string is printed, with each string separated by + a comma in the output. + + Examples:: + + print 3.14; + print "Results", x, y; + + By default, the "print" statement writes to the standard + output (stdout). However, if the first expression is of type + :bro:type:`file`, then "print" writes to that file. + + If a string contains non-printable characters (i.e., byte values that are + not in the range 32 - 126), then the "print" statement converts each + non-printable character to an escape sequence before it is printed. + + For more control over how the strings are formatted, see the :bro:id:`fmt` + function. + +.. bro:keyword:: return + + The "return" statement immediately exits the current function, hook, or + event handler. For a function, the specified expression (if any) is + evaluated and returned. A "return" statement in a hook or event handler + cannot return a value because event handlers and hooks do not have + return types. + + Examples:: + + function my_func(): string + { + return "done"; + } + + event my_event(n: count) + { + if ( n == 0 ) return; + + print n; + } + + There is a special form of the "return" statement that is only allowed + in functions. Syntactically, it looks like a :bro:keyword:`when` statement + immediately preceded by the "return" keyword. This form of the "return" + statement is used to specify a function that delays its result (such a + function can only be called in the expression of a :bro:keyword:`when` + statement). The function returns at the time the "when" + statement's condition becomes true, and the function returns the value + that the "when" statement's body returns (or if the condition does + not become true within the specified timeout interval, then the function + returns the value that the "timeout" block returns). + + Example:: + + global X: table[string] of count; + + function a() : count + { + # This delays until condition becomes true. + return when ( "a" in X ) + { + return X["a"]; + } + timeout 30 sec + { + return 0; + } + } + + event bro_init() + { + # Installs a trigger which fires if a() returns 42. + when ( a() == 42 ) + print "expected result"; + + print "Waiting for a() to return..."; + X["a"] = 42; + } + + +.. bro:keyword:: schedule + + The "schedule" statement is used to raise a specified event with + specified parameters at a later time specified as an :bro:type:`interval`. + + Example:: + + schedule 30sec { myevent(x, y, z) }; + + Note that the braces are always required (they do not indicate a + `compound statement`_). + + Note that "schedule" is actually an expression that returns a value + of type "timer", but in practice the return value is not used. + +.. bro:keyword:: switch + + A "switch" statement evaluates a given expression and jumps to + the first "case" label which contains a matching value (the result of the + expression must be type-compatible with all of the values in all of the + "case" labels). If there is no matching value, then execution jumps to + the "default" label instead, and if there is no "default" label then + execution jumps out of the "switch" block. + + Here is an example (assuming that "get_day_of_week" is a + function that returns a string):: + + switch get_day_of_week() + { + case "Sa", "Su": + print "weekend"; + fallthrough; + case "Mo", "Tu", "We", "Th", "Fr": + print "valid result"; + break; + default: + print "invalid result"; + break; + } + + A "switch" block can have any number of "case" labels, and one + optional "default" label. + + A "case" label can have a comma-separated list of + more than one value. A value in a "case" label can be an expression, + but it must be a constant expression (i.e., the expression can consist + only of constants). + + Each "case" and the "default" block must + end with either a :bro:keyword:`break`, :bro:keyword:`fallthrough`, or + :bro:keyword:`return` statement (although "return" is allowed only + if the "switch" statement is inside a function, hook, or event handler). + If a "case" (or "default") block contain more than one statement, then + there is no need to wrap them in braces. + + Note that the braces in a "switch" statement are always required (these + do not indicate the presence of a `compound statement`_), and that no + semicolon is needed at the end of a "switch" statement. + + +.. bro:keyword:: when + + Evaluates a given expression, which must result in a value of type + :bro:type:`bool`. When the value of the expression becomes available + and if the result is true, then a specified statement is executed. + + In the following example, if the expression evaluates to true, then + the "print" statement is executed:: + + when ( (local x = foo()) && x == 42 ) + print x; + + However, if a timeout is specified, and if the expression does not + evaluate to true within the specified timeout interval, then the + statement following the "timeout" keyword is executed:: + + when ( (local x = foo()) && x == 42 ) + print x; + timeout 5sec { + print "timeout"; + } + + Note that when a timeout is specified the braces are + always required (these do not indicate a `compound statement`_). + + The expression in a "when" statement can contain a declaration of a local + variable but only if the declaration is written in the form + "local *var* = *init*" (example: "local x = myfunction()"). This form + of a local declaration is actually an expression, the result of which + is always a boolean true value. + + The expression in a "when" statement can contain an asynchronous function + call such as :bro:id:`lookup_hostname` (in fact, this is the only place + such a function can be called), but it can also contain an ordinary + function call. When an asynchronous function call is in the expression, + then Bro will continue processing statements in the script following + the "when" statement, and when the result of the function call is available + Bro will finish evaluating the expression in the "when" statement. + See the :bro:keyword:`return` statement for an explanation of how to + create an asynchronous function in a Bro script. + + +.. _compound statement: + +**compound statement** + A compound statement is created by wrapping zero or more statements in + braces ``{ }``. Individual statements inside the braces need to be + terminated by a semicolon, but a semicolon is not needed at the end + (outside of the braces) of a compound statement. + + A compound statement is required in order to execute more than one + statement in the body of a :bro:keyword:`for`, :bro:keyword:`if`, or + :bro:keyword:`when` statement. + + Example:: + + if ( x == 2 ) { + print "x is 2"; + ++x; + } + + Note that there are other places in the Bro scripting language that use + braces, but that do not indicate the presence of a compound + statement (these are noted in the documentation). + +.. _null: + +**null statement** + The null statement (executing it has no effect) consists of just a + semicolon.

Now the right signer certificate for the reply is looked up (and no longer assumed that it is the first one) and a few compares are fixed. Plus - there are more test cases that partially send certificates in the ocsp message and partially do not - and it seems to work fine in all cases.
