2013-03-07PR gdb/15236: gdbserver write to linux memory with zero length corrupts stackPedro Alves2-1/+13
PROBLEM: The function linux_write_memory () in linux-low.c allocates a buffer on the stack to hold a copy of the data to be written. register PTRACE_XFER_TYPE *buffer = (PTRACE_XFER_TYPE *) alloca (count * sizeof (PTRACE_XFER_TYPE)); "count" is the number of bytes to be written, rounded up to the nearest multiple of sizeof (PTRACE_XFER_TYPE) and allowing for not being an aligned address. The function later uses buffer[0] = ptrace (PTRACE_PEEKTEXT, pid, (PTRACE_ARG3_TYPE) (uintptr_t) addr, 0); The problem is that this function can be called to write zero bytes on an aligned address, for example when receiving an X packet of length 0 (used to test if 8-bit write is supported). Under these circumstances, count can be zero. Since in this case, buffer[0] may never have been allocated, the stack is corrupted and gdbserver may crash. SOLUTION: Writing zero bytes should always succeed. The patch below returns successfully early if the length is zero, so avoiding the stack corruption. Verified on the ARC GDB 7.5.1 port. 2013-03-07 Jeremy Bennett <jeremy.bennett@embecosm.com> PR server/15236 * linux-low.c (linux_write_memory): Return early success if LEN is zero.

2013-03-06Garbage collect py-utils.c:target_string_to_unicode.Pedro Alves3-14/+6
The strlen in this function looked suspicious, for the function documents that STR is in the target's charset (what if it is utf-32, etc.). On closer inspection, nothing is calling the function, and it's been that way ever since the function was added. gdb/ 2013-03-06 Pedro Alves <palves@redhat.com> * python/py-utils.c (target_string_to_unicode): Delete function. * python/python-internal.h (target_string_to_unicode): Delete declaration.
2013-03-06tstatus.exp: use UNSUPPORTED for optional features that are not supportedPedro Alves2-20/+31
The current tstatus.exp tests shows PASSes if either the target support or not the optional tstatus bits: PASS: gdb.trace/tstatus.exp: tstatus does not report trace stop reason PASS: gdb.trace/tstatus.exp: tstatus reports trace stop reason The former (and any other similar case) should be UNSUPPORTED rather than PASS. That'd make it much easier to spot actually problems with the test (e.g., the one Yao's previous patch addressed), along with regressions and progressions. The "not supported" paths in tstatus.exp explicitly check for output you'd get if the feature wasn't supported, so real unexpected failures will still be caught as FAILs. So now e.g., where we wanted to check if tstatus reports the trace stop reason, and if the target does support it, we get PASS: tstatus reports trace stop reason if the target actually reports what we'd expect if the trace stop reason isn't supported, we get: UNSUPPORTED: tstatus reports trace stop reason and if the target reports something else unexpected, we get: FAIL: tstatus reports trace stop reason That has the added bonus that the test string is always the same and only the test results change (PASS/FAIL/UNSUPPORTED), which makes it easier for testers see regressions, compared to the previous: -PASS: gdb.trace/tstatus.exp: tstatus reports trace stop reason +PASS: gdb.trace/tstatus.exp: tstatus does not report trace stop reason which clearly easily goes by unnoticed, as evidenced by the existing problem Yao's previous patch addressed. Tested on x86_64 Fedora 17. gdb/testsuite/ 2013-03-06 Pedro Alves <palves@redhat.com> * gdb.trace/tstatus.exp (run_trace_experiment): When the target doesn't support the tested optional feature, call "unsupported" with the same test message as the "pass" case, instead of calling "pass" with a different message. Use the same text for the "fail" cases too.

2013-03-01Use gdb_byte for bytes from the program being debugged.Pedro Alves36-93/+167
gdb_byte should be used for bytes from the program being debugged. We have many places using char or unsigned char instead all over the existing ports, and more ends up added over time due to copy/paste as new code is based on old code.
