* scan-build: memarea_strndup() undefined behaviorNick Mathewson2014-04-19
| | | | | | | | The memarea_strndup() function would have hit undefined behavior by creating an 'end' pointer off the end of a string if it had ever been given an 'n' argument bigger than the length of the memory ares that it's scanning. Fortunately, we never did that except in the unit tests. But it's not a safe behavior to leave lying around.
* memarea.c: use flexible array member for memNick Mathewson2014-03-18
| | | | | | | | | | | | This make clang's memory sanitizer happier that we aren't reading off the end of a char[1]. We hadn't replaced the char[1] with a char[FLEXIBLE_ARRAY_MEMBER] before because we were doing a union trick to force alignment. Now we use __attribute__(aligned) where available, and we do the union trick elsewhere. Most of this patch is just replacing accesses to (x)->u.mem with (x)->U_MEM, where U_MEM is defined as "u.mem" or "mem" depending on our implementation.

This is a machine-generated patch. To make it, start by getting the list of reserved identifiers using: git ls-tree -r --name-only HEAD | grep '\.[ch]$' | \ xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \ cut -f 1 | sort| uniq You might need gnu ctags. Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change. (That is, all the C except that in src/ext.)

| * Have all of our allocation functions and a few others check for underflowNick Mathewson2010-12-13
| | | | | | | | | | | | | | | | | | It's all too easy in C to convert an unsigned value to a signed one, which will (on all modern computers) give you a huge signed value. If you have a size_t value of size greater than SSIZE_T_MAX, that is way likelier to be an underflow than it is to be an actual request for more than 2gb of memory in one go. (There's nothing in Tor that should be trying to allocate >2gb chunks.)
* | Rename log.h to torlog.hNick Mathewson2010-07-09
| | | | | | | | | | | | | | | | | | | | This should make us conflict less with system files named "log.h". Yes, we shouldn't have been conflicting with those anyway, but some people's compilers act very oddly. The actual change was done with one "git mv", by editing Makefile.am, and running find . -name '*.[ch]' | xargs perl -i -pe 'if (/^#include.*\Wlog.h/) {s/log.h/torlog.h/; }'

* | *_free functions now accept NULLSebastian Hahn2009-12-12
| | | | | | | | | | | | | | | | Some *_free functions threw asserts when passed NULL. Now all of them accept NULL as input and perform no action when called that way. This gains us consistence for our free functions, and allows some code simplifications where an explicit null check is no longer necessary.

| * Fix an assertion-failure in memarea_alloc() on 64-bit platforms.Nick Mathewson2009-05-17
| | | | | | | | | | | | | | The trick is that we should assert that our next_mem pointer has not run off the end of the array _before_ we realign the pointer, since doing that could take us over the end... but only if we're on a system where malloc() gives us ram in increments smaller than sizeof(void*).
