2018-02-11vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds297-913/+913
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

After this series, the kernel is ready for running for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done as a for bulk search-and-replace. After that, the kernel is ready to apply the patch to unify {de,}mangle_poll(), and then get rid of kernel-side POLL... uses entirely, and we should be all done with that stuff. Basically, that's what you suggested wrt KPOLL..., except that we can use EPOLL... instead - they already are arch-independent (and equal to what is currently kernel-side POLL...). After the preparations (in this series) switch to returning EPOLL... from ->poll() instances is completely mechanical and kernel-side POLL... can go away. The last step (killing kernel-side POLL... and unifying {de,}mangle_poll() has to be done after the search-and-replace job, since we need userland-side POLL... for unified {de,}mangle_poll(), thus the cherry-pick at the last step. After that we will have: - POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly)" * 'work.poll2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: annotate ep_scan_ready_list() ep_send_events_proc(): return result via esed->res preparation to switching ->poll() to returning EPOLL... add EPOLLNVAL, annotate EPOLL... and event_poll->event use linux/poll.h instead of asm/poll.h xen: fix poll misannotation smc: missing poll annotations

The commit 917538e212a2 ("kasan: clean up KASAN_SHADOW_SCALE_SHIFT usage") removed KASAN_SHADOW_SCALE_SHIFT definition from include/linux/kasan.h and added it to architecture-specific headers, except for xtensa.

Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} + For simplicity, two sed expressions were used to solve each warnings separately. To make the regex expression more robust a few other issues were resolved, namely setting unit-address to lower case, and adding a whitespace before the the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation") Reported-by: David Daney <ddaney@caviumnetworks.com> Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Malaterre <malat@debian.org> Acked-by: Ley Foon Tan <ley.foon.tan@intel.com>

59f47eff03a0 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") replaced of_irq_parse_pci() + irq_create_of_mapping() with of_irq_parse_and_map_pci(), but neglected to capture the virq returned by irq_create_of_mapping(), so virq remained zero, which caused INTx configuration to fail.

Here the chunk size for INIT_ACK packet becomes too big, mostly because of the state cookie (INIT packet has large size with many address parameters), plus additional server parameters. Later this chunk causes the panic in skb_put_data(): skb_packet_transmit() sctp_packet_pack() skb_put_data(nskb, chunk->skb->data, chunk->skb->len); 'nskb' (head skb) was previously allocated with packet->size from u16 'chunk->chunk_hdr->length'. As suggested by Marcelo we should check the chunk's length in _sctp_make_chunk() before trying to allocate skb for it and discard a chunk if its size bigger than SCTP_MAX_CHUNK_LEN.

2018-02-09s390/qeth: fix underestimated count of buffer elementsUrsula Braun1-1/+1
For a memory range/skb where the last byte falls onto a page boundary (ie. 'end' is of the form xxx...xxx001), the PFN_UP() part of the calculation currently doesn't round up to the next PFN due to an off-by-one error. Thus qeth believes that the skb occupies one page less than it actually does, and may select a IO buffer that doesn't have enough spare buffer elements to fit all of the skb's data. HW detects this as a malformed buffer descriptor, and raises an exception which then triggers device recovery.

2018-02-09net: stmmac: remove redundant enable of PMT irqNiklas Cassel2-4/+1
For dwmac4, GMAC_INT_DEFAULT_ENABLE already includes GMAC_INT_PMT_EN, so it is redundant to check if hw->pmt is set, and if so, setting the bit again. For dwmac1000, GMAC_INT_DEFAULT_MASK does not include GMAC_INT_DISABLE_PMT, so it is redundant to check if hw->pmt is set, and if so, clearing an already cleared bit.

2018-02-09net: stmmac: discard disabled flags in interrupt status registerNiklas Cassel1-2/+4
The interrupt status register in both dwmac1000 and dwmac4 ignores interrupt enable (for dwmac4) / interrupt mask (for dwmac1000). Therefore, if we want to check only the bits that can actually trigger an irq, we have to filter the interrupt status register manually. Commit 0a764db10337 ("stmmac: Discard masked flags in interrupt status register") fixed this for dwmac1000. Fix the same issue for dwmac4. Just like commit 0a764db10337 ("stmmac: Discard masked flags in interrupt status register"), this makes sure that we do not get spurious link up/link down prints.

2018-02-09ibmvnic: Reset long term map ID counterThomas Falcon1-0/+1
When allocating RX or TX buffer pools, the driver needs to provide a unique mapping ID to firmware for each pool. This value is assigned using a counter which is incremented after a new pool is created. The ID can be an integer ranging from 1-255. When migrating to a device that requests a different number of queues, this value was not being reset properly. As a result, after enough migrations, the counter exceeded the upper bound and pool creation failed. This is fixed by resetting the counter to one in this case.

Daniel Borkmann says: ==================== pull-request: bpf 2018-02-09 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Two fixes for BPF sockmap in order to break up circular map references from programs attached to sockmap, and detaching related sockets in case of socket close() event. For the latter we get rid of the smap_state_change() and plug into ULP infrastructure, which will later also be used for additional features anyway such as TX hooks. For the second issue, dependency chain is broken up via map release callback to free parse/verdict programs, all from John. 2) Fix a libbpf relocation issue that was found while implementing XDP support for Suricata project. Issue was that when clang was invoked with default target instead of bpf target, then various other e.g. debugging relevant sections are added to the ELF file that contained relocation entries pointing to non-BPF related sections which libbpf trips over instead of skipping them. Test cases for libbpf are added as well, from Jesper. 3) Various misc fixes for bpftool and one for libbpf: a small addition to libbpf to make sure it recognizes all standard section prefixes. Then, the Makefile in bpftool/Documentation is improved to explicitly check for rst2man being installed on the system as we otherwise risk installing empty man pages; the man page for bpftool-map is corrected and a set of missing bash completions added in order to avoid shipping bpftool where the completions are only partially working, from Quentin. 4) Fix applying the relocation to immediate load instructions in the nfp JIT which were missing a shift, from Jakub. 5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL in this case; and explicitly delete the veth devices in the two tests test_xdp_{meta,redirect}.sh before dismantling the netnses as when selftests are run in batch mode, then workqueue to handle destruction might not have finished yet and thus veth creation in next test under same dev name would fail, from Yonghong. 6) Fix test_kmod.sh to check the test_bpf.ko module path before performing an insmod, and fallback to modprobe. Especially the latter is useful when having a device under test that has the modules installed instead, from Naresh. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
