2009-06-16raw-posix: Remove O_RDWR when attempting to open a file read-onlyAvi Kivity1-0/+1
When we open a file, we first attempt to open it read-write, then fall back to read-only. Unfortunately we reuse the flags from the previous attempt, so both attempts try to open the file with write permissions, and fail. Fix by clearing the O_RDWR flag from the previous attempt.

2009-06-16raw-posix: open flags use BDRV_ namespace, not posix namespaceAvi Kivity1-1/+1

2009-06-16linux-user: remove duplicate tswap32() from do_getsockopt()Laurent Vivier1-1/+0
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". So the "val = tswap32(val);" is useless and wrong. This patch removes it. Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2009-06-16RFC: fix fcntl support in linux-user - new tryArnaud Patard (Rtp)2-24/+73
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 Patard1-1/+2
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 Patard1-0/+2
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).

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.

2009-06-15raw-posix: cleanup ioctl methodsChristoph Hellwig1-34/+8
Rename raw_ioctl and raw_aio_ioctl to hdev_ioctl and hdev_aio_ioctl as they are only used for the host device. Also only add them to the method table for the cases where we need them (generic hdev if linux and linux CDROM) instead of declaring stubs and always add them.

2009-06-15block: add bdrv_probe_device methodChristoph Hellwig4-32/+74
Add a bdrv_probe_device method to all BlockDriver instances implementing host devices to move matching of host device types into the actual drivers. For now we keep exacly the old matching behaviour based on the devices names, although we really should have better detetion methods based on device information in the future. Signed-off-by: Christoph Hellwig <hch@lst.de>
2009-06-15raw-posix: split hdev driversChristoph Hellwig2-277/+347
Instead of declaring one BlockDriver for all host devices declared one for each type: a generic one for normal disk devices, a Linux floppy driver and a CDROM driver for Linux and FreeBSD. This gets rid of a lot of messy ifdefs and switching based on the type in the various removal device methods. block.c grows a new method to find the correct host device driver based on OS-sepcific criteria, which will later into the actual drivers in a later patch in this series.

2009-06-15raw-posix: add a raw_open_common helperChristoph Hellwig1-29/+19
raw_open and hdev_open contain the same basic logic. Add a new raw_open_common helper containing the guts of the open routine and call it from raw_open and hdev_open. We use the new open_flags field in BDRVRawState to allow passing additional open flags to raw_open_common from both. Signed-off-by: Christoph Hellwig <hch@lst.de>
2009-06-15raw-posix: always store open flagsChristoph Hellwig1-26/+21
Both the Linux floppy and the FreeBSD CDROM host device need to store the open flags so that they can re-open the device later. Store the open flags unconditionally to remove the ifdef mess and simply the calling conventions for the later patches in the series. Signed-off-by: Christoph Hellwig <hch@lst.de>

2009-06-13migrate_fd_close: delete associated io-handler before closing the fdUri Lublin1-0/+2
It may happen that the io-handler is still registered. That causes select() to return with EBADF, not calling handlers for other fds. The io-handler would be registered when (on the source) the whole state was written but not yet flushed. For example when using QEMUFileBuffered, (tcp-migration) there may be data left in a buffer waiting to be transferred. In such a case buffered_close() calls buffered_flush() which calls migrate_fd_put_buffer, which may, upon EAGAIN, register migrate_fd_put_notify as a handler.

2009-06-13Don't use cpu_index as apic_id.Gleb Natapov3-13/+40
(patch is on top of "Apic creation should not depend on pci" series) Currently cpu_index is used as cpu apic id on x86. This is incorrect since apic ids not have to be continuous (they can also encode cpu hierarchy information). This patch uses cpuid_apic_id for initial apic id value. For now cpuid_apic_id is set to be equal to cpu_index so behaviour is fully backward compatible, but it allows us to add qemu option to provide other values for cpu apic id.

2009-06-13Fix SDL include path.Stefan Weil2-2/+2
SDL header files can be included in two different ways: * like this: #include <SDL/SDL.h> * like this: #include <SDL.h> The 1st alternative is simple and works in many cases. The 2nd alternative needs sdl-config to get the correct compiler flags. It is the recommended way to write SDL includes and standard for QEMU. The patch fixes two non-standard SDL includes.
