[PATCH 1/2] Advertise obstack only when chosen
by Anton Kolesov 24 Feb '16

24 Feb '16

This is similar to this patch for GNU glob: ff6ce3999db93a52d1cd22510f8508b660ddf54e. The problem is that libiberty/obstack.c file checks for _GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides libiberty obstack implementation if there is already a compatible implementation in libc. Therefore define should be set only when obstack is actually selected, otherwise it is not possible to build binutils and gdb with uClibc.

[PATCH] xtensa: fix stack unwinding over __default_sa_restorer
by Max Filippov 24 Feb '16

24 Feb '16

For some xtensa cores generated code gets arranged so that __default_sa_restorer immediately follows preceding function.

Signal stack frame is not recognized and is not unwound properly, breaking cleanup routines calling for cancelled thread. Insert padding before the __default_sa_restorer so that no FDE is found for it, MD_FALLBACK_FRAME_STATE_FOR is called by uw_frame_state_for and the frame is correctly recognized as signal frame.

This is not needed after earlier patch which removes invalid _GNU_OBSTACK_INTERFACE_VERSION definition in cases when obstack is not selected in uClibc configuration. With this change binutils and GDB would use obstack implementation from their own source trees. In fact with recent binutils it is not possible to build it using obstack implementation in uClibc, because binutils/include/obstack.h started to use _obstack_free function instead of obstack_free, but _obstack_free is not defined in uClibc.

[uclibc-ng] transmission 2.84 crash on MIPSEL with uClibc-ng 1.0.10-1.0.12
by Alex Potapenko 21 Feb '16

21 Feb '16

Hi, After I upgraded uClibc-ng from 1.0.9 to 1.0.10 for MIPSEL, I get some segfaults that didn't happen before the upgrade. And this happens with 1.0.11-1.0.12 too. I attached transmission 2.84 gdb crash log. The crash happens some while after a torrent is initiated. I tested this with 1.0.10-1.0.11 too (the log is from 1.0.12), and got the same issue. If I downgrade to 1.0.9, transmission works OK. There's something wrong for other programs too, e.g., deluge keeps spawning 'sslv3 alert bad certificate' error during daemon-client handshake. pyload crashes as well (not tested by me, but I have user reports). ARMv7 uClibc-ng 1.0.12 platform doesn't have these issues. Let me know if there's more info that you need. Thanks, Alex
