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.

2013-02-19gdbserver:server.c - use unpack_varlen_hex to extract hex numbers.Pedro Alves2-5/+17
Addresses, as most numbers in the RSP are hex encoded, with variable length (that just means the width isn't specified, and there's no top cap. So they should be extracted with unpack_varlen_hex. A couple spots in server.c are using strto(u)l, which doesn't work on LLP64 targets. This patch fixes it.

We have over 10x more files with (C) than without in gdb's code, so I spent a few minutes grepping and fixing. Funny enough, the testsuite has it backwards.
