| | | | | | | | | | | | | | | | | | | Do generic processing even for drivers which define .bdrv_check_perm handler. It's needed for further preallocate filter: it will need to do additional action on bdrv_check_perm, but don't want to reimplement generic logic. The patch doesn't change existing behaviour: the only driver that implements bdrv_check_perm is file-posix, but it never has any children. Also, bdrv_set_perm() don't stop processing if driver has .bdrv_set_perm handler as well.

* block: bdrv_mark_request_serialising: split non-waiting functionVladimir Sementsov-Ogievskiy2020-12-183-14/+26
| | | | | | | | | | | | | | | | | | We'll need a separate function, which will only "mark" request serialising with specified align but not wait for conflicting requests. So, it will be like old bdrv_mark_request_serialising(), before merging bdrv_wait_serialising_requests_locked() into it. To reduce the possible mess, let's do the following: Public function that does both marking and waiting will be called bdrv_make_request_serialising, and private function which will only "mark" will be called tracked_request_set_serialising().

* block/io.c: drop assertion on double waiting for request serialisationVladimir Sementsov-Ogievskiy2020-12-181-10/+1Star
| | | | | | | | | | | | | | | | | The comments states, that on misaligned request we should have already been waiting. But for bdrv_padding_rmw_read, we called bdrv_mark_request_serialising with align = request_alignment, and now we serialise with align = cluster_size. So we may have to wait again with larger alignment. Note, that the only user of BDRV_REQ_SERIALISING is backup which issues cluster-aligned requests, so seems the assertion should not fire for now. But it's wrong anyway.

* block: drop tighten_restrictionsVladimir Sementsov-Ogievskiy2020-12-181-72/+17Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only users of this thing are: 1. bdrv_child_try_set_perm, to ignore failures on loosen restrictions 2. assertion in bdrv_replace_child 3. assertion in bdrv_inactivate_recurse Assertions are not enough reason for overcomplication the permission update system. So, look at bdrv_child_try_set_perm. We are interested in tighten_restrictions only on failure. But on failure this field is not reliable: we may fail in the middle of permission update, some nodes are not touched and we don't know should their permissions be tighten or not. So, we rely on the fact that if we loose restrictions on some node (or BdrvChild), we'll not tighten restriction in the whole subtree as part of this update (assertions 2 and 3 rely on this fact as well). And, if we rely on this fact anyway, we can just check it on top, and don't pass additional pointer through the whole recursive infrastructure. Note also, that further patches will fix real bugs in permission update system, so now is good time to simplify it, as a help for further refactorings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent binutils changes dropping unsupported options [1] caused a build issue in regard to the optionroms. ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \ -s -o multiboot.img multiboot.o ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?) This isn't really a regression in ld.bfd, filing the bug upstream revealed that this never worked as a ld flag [2] - in fact it seems we were by accident setting --nmagic). Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be droppable without any effect. This also is the only use-case of LDFLAGS_NOPIE in .mak, therefore we can also remove it from being added there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit efc6c07 ("configure: Add a test for the minimum compiler version"), QEMU explicitely depends on GCC >= 4.8, we could thus drop earlier version checks. Except clang advertizes itself as GCC 4.2.1. Since clang doesn't support gnu_printf, make that case explicitely and drop GCC version check.
