* bhyve: avoid TOCTOU on iov_len in virtio_vq_recordon()Pierre Pronchery2024-09-271-3/+8
| | | | | | | | | | | | | | | Avoid a race condition when accessing guest memory, by reading memory contents only once. This has also been applied to _vq_record() in sys/dev/beri/virtio/virtio.c, as per markj@'s suggestion.

* Although most of the NIC drivers are epoch ready, due to peer pressureGleb Smirnoff2020-02-241-1/+1
| | | | | | | | | | | | | | | | | | | switch over to opt-in instead of opt-out for epoch. Instead of IFF_NEEDSEPOCH, provide IFF_KNOWSEPOCH. If driver marks itself with IFF_KNOWSEPOCH, then ether_input() would not enter epoch when processing its packets. Now this will create recursive entrance in epoch in >90% network drivers, but will guarantee safeness of the transition. Mark several tested drivers as IFF_KNOWSEPOCH.

* vfs: introduce v_irflag and make v_type smallerMateusz Guzik2019-12-081-1/+1
| | | | | | | | | | | | | | | | | | The current vnode layout is not smp-friendly by having frequently read data avoidably sharing cachelines with very frequently modified fields. In particular v_iflag inspected for VI_DOOMED can be found in the same line with v_usecount. Instead make it available in the same cacheline as the v_op, v_data and v_type which all get read all the time. v_type is avoidably 4 bytes while the necessary data will easily fit in 1. Shrinking it frees up 3 bytes, 2 of which get used here to introduce a new flag field with a new value: VIRF_DOOMED.

* Fix off-by-one error in BERI virtio driverOleksandr Tymoshenko2019-02-111-2/+2
| | | | | | | | | | | | | | | | | | The hardcoded ident is exactly 20 bytes long but sprintf adds terminating zero, so there is one byte written out of array bounds.As a fix use strncpy it appends \0 only if space allows and its behavior matches virtio spec: When VIRTIO_BLK_T_GET_ID is issued, the device identifier, up to 20 bytes, is written to the buffer. The identifier should be interpreted as an ascii string. It is terminated with \0, unless it is exactly 20 bytes long.

* Revert r327828, r327949, r327953, r328016-r328026, r328041:Pedro F. Giffuni2018-01-211-1/+1
| | | | | | | | | | | | | | | | | | Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197 Notes: svn path=/head/; revision=328218
* dev: make some use of mallocarray(9).Pedro F. Giffuni2018-01-131-1/+1
| | | | | | | | | | | | | | Focus on code where we are doing multiplications within malloc(9). None of these is likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values. Notes: svn path=/head/; revision=327949
