2019-02-07slirp: replace global polling with per-instance & notifierMarc-André Lureau7-309/+333
Remove hard-coded dependency on slirp in main-loop, and use a "poll" notifier instead. The notifier is registered per slirp instance. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>

2019-02-07slirp: Don't mark struct ipq or struct ipasfrag as packedPeter Maydell1-2/+5
There is no reason to mark the struct ipq and struct ipasfrag as packed: they are naturally aligned anyway, and are not representing any on-the-wire packet format. Indeed they vary in size depending on the size of pointers on the host system, because the 'struct qlink' members include 'void *' fields. Dropping the 'packed' annotation fixes clang -Waddress-of-packed-member warnings and probably lets the compiler generate better code too. The only thing we do care about in the layout of the struct is that the frag_link matches up with the ipf_link of the struct ipasfrag, as documented in the comment on that struct; assert at build time that this is the case.

2019-02-07slirp: Avoid marking naturally packed structs as QEMU_PACKEDPeter Maydell2-7/+25
Various ipv6 structs in the slirp headers are marked QEMU_PACKED, but they are actually naturally aligned and will have no padding in them. Instead of marking them with the 'packed' attribute, assert at compile time that they are the size we expect. This allows us to take the address of fields within the structs without risking undefined behaviour, and suppresses clang -Waddress-of-packed-member warnings.

Coverity warns (CID 1390634) that open_net_route() is not checking the return value from sscanf(), which means that it might then use values that aren't initialized. Errors here should in general not happen since we're passing an assumed-good /proc/net/route from the host kernel, but if we do fail to parse a line then just skip it in the output we pass to the guest.

2019-02-06accel/tcg: Consider cluster index in tb_lookup__cpu_state()Peter Maydell2-3/+4
In commit f7b78602fdc6c6e4be we added the CPU cluster number to the cflags field of the TB hash; this included adding it to the value kept in tb->cflags, since we pass that field directly into the hash calculation in some places. Unfortunately we forgot to check whether other parts of the code were doing comparisons against tb->cflags that would need to be updated. It turns out that there is exactly one such place: the tb_lookup__cpu_state() function checks whether the TB it has found in the tb_jmp_cache has a tb->cflags matching the cf_mask that is passed in. The tb->cflags has the cluster_index in it but the cf_mask does not. Hoist the "add cluster index to the cf_mask" code up from tb_htable_lookup() to tb_lookup__cpu_state() so it can be considered in the "did this TB match in the jmp cache" condition, as well as when we do the full hash lookup by physical PC, flags, etc. (tb_htable_lookup() is only called from tb_lookup__cpu_state(), so this change doesn't require any further knock-on changes.)
