2012-01-15libc: build abort with unwind-info for backtraceBernhard Reutner-Fischer
If backtrace support is turned on, build raise() and abort() with unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-01-14linuxthreads/signals: do not restore handler for invalid signalMarkos Chandras
Invalid signals have no handlers so when trying to restore the old handler to a bad signal a SIGSEGV occurs. This is because the library tries to store the old handler to an invalid memory area where it things the bad signal lives.

2012-01-14buildsys: cache build flags in varsMike Frysinger
Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags. Add some helpers to automate the process of setting up variables to cache the result of tests, as well as the checking of an already set flag. Now `make clean` takes like 2 seconds on my system.

2012-01-13libubacktrace: use -asynchronous-funwind-tables rather than -funwind-tablesCarmelo Amoroso
From gcc documentation, we can read: " ... -fasynchronous-unwind-tables Generate unwind table in dwarf2 format, if supported by target machine. The table is exact at each instruction boundary, so it can be used for stack unwinding from asynchronous events (such as debugger or garbage collector) ..." So it seems better rather than using -funwind-tables (glibc seems to prefer -fasynchronous-unwind-tables).

2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function. Impacts in terms of size are really limited Current text data bss dec hex filename 164 0 0 164 a4 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.os 164 0 0 164 a4 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.oS 220 24 4 248 f8 ./libc/stdlib/abort.os With (-fasynchronous-unwind-tables) text data bss dec hex filename 216 0 0 216 d8 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.os 216 0 0 216 d8 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.oS 280 24 4 308 134 ./libc/stdlib/abort.os Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com> Acked-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-01-02ldso: setup search path even when there are no "/"Mike Frysinger
If people use an interp path such as "ld.so", then there is no "/" found, and we end up dereferencing a NULL pointer. Simplify the logic by having a relative interp path like that be the same as "" (which the code later on interprets as $PWD). While we're here, document some of the nuances of this code.

2012-01-02ldso: simplify interp path search logicMike Frysinger
The setup logic is duplicated, so unify it in a local func. Mark the variable const while we're doing this, and add missing ifdef protection to the header that declares it availability. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-12-22libcrypt: add support for SHA256-CRYPT password hashingWilliam Pitcock
This is based on Ulrich Drepper's implementation in GLIBC, but hacked up to work in uClibc. The differences from the GLIBC version are as follows: - b64_from_24bit() has been converted into a macro - Usage of GLIBC-isms (such as libc_freeres_ptr) have been removed It is enabled by the UCLIBC_HAS_SHA256_CRYPT_IMPL configuration symbol. You must have UCLIBC_HAS_CRYPT_IMPL enabled as well. Signed-off-by: William Pitcock <nenolod@dereferenced.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
