2017-09-19Convert multi-line fprintf() to warn_report()Alistair Francis2-12/+11
Convert all the multi-line uses of fprintf(stderr, "warning:"..."\n"... to use warn_report() instead. This helps standardise on a single method of printing warnings to the user. All of the warnings were changed using these commands: find ./* -type f -exec sed -i \ 'N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \ {} + Indentation fixed up manually afterwards. Some of the lines were manually edited to reduce the line length to below 80 charecters. Some of the lines with newlines in the middle of the string were also manually edit to avoid checkpatch errrors. The #include lines were manually updated to allow the code to compile. Several of the warning messages can be improved after this patch, to keep this patch mechanical this has been moved into a later patch.

After the patch, the effect like this: $ ./x86_64-softmmu/qemu-system-x86_64 -net socket,mcast=230.0.0.1:1234,listen qemu-system-x86_64: -net socket,mcast=230.0.0.1:1234,listen: exactly one of listen=, connect=, mcast= or udp= is requireda This also fixes a few silent failures to report an error.

2017-09-08net/socket: Don't treat odd socket type as SOCK_STREAMMao Zhongyi1-3/+3
In net_socket_fd_init(), the 'default' case is odd: it warns, then continues as if the socket type was SOCK_STREAM. The comment explains "this could be a eg. a pty", but that makes no sense. If @fd really was a pty, getsockopt() would fail with ENOTSOCK. If @fd was a socket, but neither SOCK_DGRAM nor SOCK_STREAM. It should not be treated as if it was SOCK_STREAM. Turn this case into an Error. If there is a genuine reason to support something like SOCK_RAW, it should be explicitly handled.

Convert all uses of error_report("warning:"... to use warn_report() instead. This helps standardise on a single method of printing warnings to the user. All of the warnings were changed using these two commands: find ./* -type f -exec sed -i \ 's|error_report(".*warning[,:] |warn_report("|Ig' {} + Indentation fixed up manually afterwards. The test-qdev-global-props test case was manually updated to ensure that this patch passes make check (as the test cases are case sensitive).

2017-06-07Revert "Change net/socket.c to use socket_*() functions" againDaniel P. Berrange1-71/+56
This reverts commit 883e4f7624e10b98d16d9adaffb8b1795664d899. This code changed net/socket.c from using socket()+connect(), to using socket_connect(). In theory this is great, but in practice this has completely broken the ability to connect the frontend and backend: $ ./x86_64-softmmu/qemu-system-x86_64 \ -device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05 \ -netdev socket,id=hn0,connect=localhost:1234 qemu-system-x86_64: -device e1000,id=e0,netdev=hn0,mac=DE:AD:BE:EF:AF:05: Property 'e1000.netdev' can't find value 'hn0' The old code would call net_socket_fd_init() synchronously, while letting the connect() complete in the backgorund. The new code moved net_socket_fd_init() so that it is only called after connect() completes in the background. Thus at the time we initialize the NIC frontend, the backend does not exist. The socket_connect() conversion as done is a bad fit for the current code, since it did not try to change the way it deals with async connection completion. Rather than try to fix this, just revert the socket_connect() conversion entirely. The code is about to be converted to use QIOChannel which will let the problem be solved in a cleaner manner. This revert is more suitable for stable branches in the meantime. Signed-off-by: Daniel P.

2017-06-02char: make chr_fe_deinit() optionaly delete backendMarc-André Lureau3-12/+7
This simplifies removing a backend for a frontend user (no need to retrieve the associated driver and separate delete call etc). NB: many frontends have questionable handling of ending a chardev. They should probably delete the backend to prevent broken reusage. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

Make qemu_chr_replay() a macro shared by both char and char-fe.
