2009-07-08linux-user: check some parameters for some socket syscalls.Arnaud Patard
This patch is fixing following issues : - commit 8fea36025b9d6d360ff3b78f88a84ccf221807e8 was applied to do_getsockname instead of do_accept. - Some syscalls were not checking properly the memory addresses passed as argument - Add check before syscalls made for cases like do_getpeername() where we're using the address parameter after doing the syscall - Fix do_accept to return EINVAL instead of EFAULT when parameters invalid to match with linux behaviour Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
2009-07-08linux-user: increment MAX_ARG_PAGESArnaud Patard
There's a error When doing something like that : find / -type f -print0 | xargs -0 echo [ done in a arm chroot with qemu-arm and linux binfmt stuff or with find / -type f -print0 | qemu-arm -L <path> <path>/usr/bin/xargs -0 echo ] Doing this outsite qemu is fine. The problem was the huge number of parameters. Increasing MAX_ARG_PAGES is fixing that. While I was at it, I've modified linux-user/main.c to report error code of loader_exec.

2009-06-16linux-user: remove duplicate tswap32() from do_getsockopt()Laurent Vivier
This issue has been detected with tests/linux-tests.c: linux-test.c:330: getsockopt 327 len = sizeof(val); 328 chk_error(getsockopt(server_fd, SOL_SOCKET, SO_TYPE, &val, &len)); 329 if (val != SOCK_STREAM) 330 error("getsockopt"); In linux-user/syscall.c:do_getsockopt(), we have: ... val = tswap32(val); ... if (put_user_u32(val, optval_addr)) ... whereas "put_user_u32" calls in the end "__put_user" which uses "tswap32".

Hi, This is a new try to fix the fcntl support in linux-user. I tried to adress all comments but as the previous version is several weeks old, it's possible that I've missed some. This patch doesn't handle linux specific fcntl flags. My plan is to get this version of the patch reviewed/fixed and then, add them if wanted.

2009-06-16Return EOPNOTSUPP instead of ENOSYS for *xattr* syscallsArnaud Patard
In current code, we're sending ENOSYS to target when a syscall for the xattrs is done. This makes applications like ls complain loudly about that and breaks scripts parsing the output. Moreover, iirc, implemented features of filesystems are are sending EOPNOTSUPP (I've not checked so I may be a little bit wrong on that...). So, I'm proposing to return -EOPNOTSUPP and make ls happy Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
2009-06-16Fix struct termios host - target translationArnaud Patard
When converting the termios structure between host and target in target_to_host_termios and host_to_target_termios, the c_cc[] array is never initialised. Calling memset() before using it allows to run successfully "stty echo / stty -echo" on arm-linux-user target (host being x86 and mips).

2009-06-16linux-user: fix utimensatRiku Voipio
The glibc function for utimensat glibc returns -EINVAL when the path is null which is a different behaviour with the syscall. path can be null because internally the glibc is using utimensat with path null when implmenting futimens. If path is null, call futimes instead. don't try to copy timespec from user if is NULL. Add configure check for older systems Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2009-06-04fix gdbstub support for multiple threads in usermode, v3Nathan Froyd
When debugging multi-threaded programs, QEMU's gdb stub would report the correct number of threads (the qfThreadInfo and qsThreadInfo packets). However, the stub was unable to actually switch between threads (the T packet), since it would report every thread except the first as being dead. Furthermore, the stub relied upon cpu_index as a reliable means of assigning IDs to the threads. This was a bad idea; if you have this sequence of events: initial thread created new thread #1 new thread #2 thread #1 exits new thread #3 thread #3 will have the same cpu_index as thread #1, which would confuse GDB. (This problem is partly due to the remote protocol not having a good way to send thread creation/destruction events.) We fix this by using the host thread ID for the identifier passed to GDB when debugging a multi-threaded userspace program. The thread ID might wrap, but the same sort of problems with wrapping thread IDs would come up with debugging programs natively, so this doesn't represent a problem.
