2009-06-09net: add return value to packet receive handlerMark McLoughlin
This allows us to handle queue full conditions rather than dropping the packet on the floor. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: pass VLANClientState* as first arg to receive handlersMark McLoughlin
Give static type checking a chance to catch errors. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: re-name vc->fd_read() to vc->receive()Mark McLoughlin
VLANClientState's fd_read() handler doesn't read from file descriptors, it adds a buffer to the client's receive queue. Re-name the handlers to make things a little less confusing. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: add fd_readv() handler to qemu_new_vlan_client() argsMark McLoughlin
This, apparently, is the style we prefer - all VLANClientState should be an argument to qemu_new_vlan_client(). Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: only read from tapfd when we can sendMark McLoughlin
Reduce the number of packets dropped under heavy network traffic by only reading a packet from the tapfd when a client can actually handle it. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: vlan clients with no fd_can_read() can always receiveMark McLoughlin
If a vlan client has no fd_can_read(), that means it can always receive packets. The current code assumes it can *never* receive packets. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: move the tap buffer into TAPStateMark McLoughlin
KVM uses a 64k buffer for reading from tapfd (for GSO support) and allocates the buffer with TAPState rather than on the stack. Not allocating it on the stack probably makes sense for qemu anyway, so merge it in advance of GSO support. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: factor tap_read_packet() out of tap_send()Mark McLoughlin
Move portability clutter out into its own function. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09slirp: Reorder initializationJan Kiszka
This patch reorders the initialization of slirp itself as well as its associated features smb and redirection. So far the first reference to slirp triggered the initialization, independent of the actual -net user option which may carry additional parameters. Now we save any request to add a smb export or some redirections until the actual initialization of the stack. This also allows to move a few parameters that were passed via global variable into the argument list of net_slirp_init. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: Improve parameter error reportingJan Kiszka
As host network devices can also be instantiated via the monitor, errors should then be reported to the related monitor instead of stderr. This requires larger refactoring, so this patch starts small with introducing a helper to catch both cases and convert net_client_init as well as net_slirp_redir. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: fix error reporting for some net parameter checksMark McLoughlin
A small bit of confusion between buffers is causing errors like: qemu: invalid parameter '10' in 'script=/etc/qemu-ifup,fd=10' instead of: qemu: invalid parameter 'script' in 'script=/etc/qemu-ifup,fd=10' Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09net: Real fix for check_params usersJan Kiszka
OK, last try: 8e4416af45 broke -net socket, ffad4116b9 tried to fix it but broke error reporting of invalid parameters. So this patch widely reverts ffad4116b9 again and intead fixes those callers of check_params that originally suffered from overwritten buffers by using separate ones. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09Revert "Fix output of uninitialized strings"Mark McLoughlin
This reverts commit 8cf07dcbe7691dbe4f47563058659dba6ef66b05. This is a sorry saga. This commit: 8e4416af45 net: Add parameter checks for VLAN clients broken '-net socket' and this commit: ffad4116b9 net: Fix -net socket parameter checks fixed the problem but introduced another problem which this commit: 8cf07dcbe7 Fix output of uninitialized strings fixed that final problem, but causing us to lose some error reporting information in the process. Meanwhile Jan posted a patch to mostly re-do ffad4116b9 in a way that fixes the original issue, but without losing the error reporting information. So, let's revert 8cf07dcbe7 and apply Jan's patch. Signed-off-by: Mark McLoughlin <markmc@redhat.com>
2009-06-09slirp: Avoid zombie processes after fork_execJan Kiszka
Slirp uses fork_exec for spawning service processes, and QEMU uses this for running smbd. As SIGCHLD is not handled, these processes become zombies on termination. Fix this by installing a proper signal handler, but also make sure we disable the signal while waiting on forked network setup/shutdown scripts.

2009-06-09net: Fix and improved ordered packet deliveryJan Kiszka

2009-06-07kvm: Improve upgrade notes when facing unsupported kernelsJan Kiszka
Users complained that it is not obvious what to do when kvm refuses to build or run due to an unsupported host kernel, so let's improve the hints. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2009-06-07Use hxtool for qemu-img command listStuart Brady
Use hxtool to generate the 'command syntax' section of qemu-img's help message, and the corresponding section of the texinfo documentation. This has the side-effect of adding 'check' to this list of commands in the texinfo documentation. Signed-off-by: Stuart Brady <stuart.brady@gmail.com>

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.

2009-05-28User networking: Show active connectionsAlexander Graf
In case you're wondering what connections exactly you have open or maybe redir'ed in the past, you can't really find out from qemu right now. This patch enables you to see all current connections the host only networking holds open, so you can kill them using the previous patch.

2009-05-27User Networking: Enable removal of redirectionsAlexander Graf
Using the new host_net_redir command you can easily create redirections on the fly while your VM is running. While that's great, it's missing the removal of redirections, in case you want to have a port closed again at a later point in time. This patch adds support for removal of redirections.
