Pull zstd fixes from Nick Terrell: "Fix stack usage on parisc & improve code size bloat This contains three commits: 1. Fixes a minor unused variable warning reported by Kernel test robot [0]. 2. Improves the reported code bloat (-88KB / 374KB) [1] by outlining some functions that are unlikely to be used in performance sensitive workloads. 3. Fixes the reported excess stack usage on parisc [2] by removing -O3 from zstd's compilation flags. -O3 triggered bugs in the hppa-linux-gnu gcc-8 compiler. -O2 performance is acceptable: neutral compression, about -1% decompression speed. We also reduce code bloat (-105KB / 374KB). After this our code bloat is cut from 374KB to 105KB with gcc-11. If we wanted to cut the remaining 105KB we'd likely have to trade signicant performance, so I want to say that this is enough for now. We should be able to get further gains without sacrificing speed, but that will take some significant optimization effort, and isn't suitable for a quick fix. I've opened an upstream issue [3] to track the code size, and try to avoid future regressions, and improve it in the long term" Link: https://lore.kernel.org/linux-mm/202111120312.833wII4i-lkp@intel.com/T/ [0] Link: https://lkml.org/lkml/2021/11/15/710 [1] Link: https://lkml.org/lkml/2021/11/14/189 [2] Link: https://github.com/facebook/zstd/issues/2867 [3] Link: https://lore.kernel.org/r/20211117014949.1169186-1-nickrterrell@gmail.com/ Link: https://lore.kernel.org/r/20211117201459.1194876-1-nickrterrell@gmail.com/ * tag 'zstd-for-linus-5.16-rc1' of git://github.com/terrelln/linux: lib: zstd: Don't add -O3 to cflags lib: zstd: Don't inline functions in zstd_opt.c lib: zstd: Fix unused variable warning

After the update to zstd-1.4.10 passing -O3 is no longer necessary to get good performance from zstd. Using the default optimization level -O2 is sufficient to get good performance. I've measured no significant change to compression speed, and a ~1% decompression speed loss, which is acceptable. This fixes the reported parisc -Wframe-larger-than=1536 errors [0]. The gcc-8-hppa-linux-gnu compiler performed very poorly with -O3, generating stacks that are ~3KB. With -O2 these same functions generate stacks in the < 100B, completely fixing the problem. Function size deltas are listed below: ZSTD_compressBlock_fast_extDict_generic: 3800 -> 68 ZSTD_compressBlock_fast: 2216 -> 40 ZSTD_compressBlock_fast_dictMatchState: 1848 -> 64 ZSTD_compressBlock_doubleFast_extDict_generic: 3744 -> 76 ZSTD_fillDoubleHashTable: 3252 -> 0 ZSTD_compressBlock_doubleFast: 5856 -> 36 ZSTD_compressBlock_doubleFast_dictMatchState: 5380 -> 84 ZSTD_copmressBlock_lazy2: 2420 -> 72 Additionally, this improves the reported code bloat [1]. With gcc-11 bloat-o-meter shows an 80KB code size improvement: ``` > ../scripts/bloat-o-meter vmlinux.old vmlinux add/remove: 31/8 grow/shrink: 24/155 up/down: 25734/-107924 (-82190) Total: Before=6418562, After=6336372, chg -1.28% ``` Compared to before the zstd-1.4.10 update we see a total code size regression of 105KB, down from 374KB at v5.16-rc1: ``` > ../scripts/bloat-o-meter vmlinux.old vmlinux add/remove: 292/62 grow/shrink: 56/88 up/down: 235009/-127487 (107522) Total: Before=6228850, After=6336372, chg +1.73% ``` [0] https://lkml.org/lkml/2021/11/15/710 [1] https://lkml.org/lkml/2021/11/14/189 Link: https://lore.kernel.org/r/20211117014949.1169186-4-nickrterrell@gmail.com/ Link: https://lore.kernel.org/r/20211117201459.1194876-4-nickrterrell@gmail.com/Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Geert Uytterhoeven <geert@linux-m68k.org> Reviewed-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Nick Terrell <terrelln@fb.com>

`zstd_opt.c` contains the match finder for the highest compression levels. These levels are already very slow, and are unlikely to be used in the kernel. If they are used, they shouldn't be used in latency sensitive workloads, so slowing them down shouldn't be a big deal. This saves 188 KB of the 288 KB regression reported by Geert Uytterhoeven [0]. I've also opened an issue upstream [1] so that we can properly tackle the code size issue in `zstd_opt.c` for all users, and can hopefully remove this hack in the next zstd version we import.

The variable `litLengthSum` is only used by an `assert()`, so when asserts are disabled the compiler doesn't see any usage and warns. This issue is already fixed upstream by PR #2838 [0]. It was reported by the Kernel test robot in [1]. Another approach would be to change zstd's disabled `assert()` definition to use the argument in a disabled branch, instead of ignoring the argument. I've avoided this approach because there are some small changes necessary to get zstd to build, and I would want to thoroughly re-test for performance, since that is slightly changing the code in every function in zstd. It seems like a trivial change, but some functions are pretty sensitive to small changes. However, I think it is a valid approach that I would like to see upstream take, so I've opened Issue #2868 to attempt this upstream. Lastly, I've chosen not to use __maybe_unused because all code in lib/zstd/ must eventually be upstreamed. Upstream zstd can't use __maybe_unused because it isn't portable across all compilers.

Pull setattr idmapping fix from Christian Brauner: "This contains a simple fix for setattr. When determining the validity of the attributes the ia_{g,u}id fields contain the value that will be written to inode->i_{g,u}id. When the {g,u}id attribute of the file isn't altered and the caller's fs{g,u}id matches the current {g,u}id attribute the attribute change is allowed. The value in ia_{g,u}id does already account for idmapped mounts and will have taken the relevant idmapping into account. So in order to verify that the {g,u}id attribute isn't changed we simple need to compare the ia_{g,u}id value against the inode's i_{g,u}id value. This only has any meaning for idmapped mounts as idmapping helpers are idempotent without them. And for idmapped mounts this really only has a meaning when circular idmappings are used, i.e. mappings where e.g. id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such ciruclar mappings can e.g. be useful when sharing the same home directory between multiple users at the same time. Before this patch we could end up denying legitimate attribute changes and allowing invalid attribute changes when circular mappings are used. To even get into this situation the caller must've been privileged both to create that mapping and to create that idmapped mount. This hasn't been seen in the wild anywhere but came up when expanding the fstest suite during work on a series of hardening patches. All idmapped fstests pass without any regressions and we're adding new tests to verify the behavior of circular mappings. The new tests can be found at [1]" Link: https://lore.kernel.org/linux-fsdevel/20211109145713.1868404-2-brauner@kernel.org [1] * tag 'fs.idmapped.v5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: handle circular mappings correctly

The definition of macro MOTO_SROM_BUG is: #define MOTO_SROM_BUG (lp->active == 8 && (get_unaligned_le32( dev->dev_addr) & 0x00ffffff) == 0x3e0008) and the if statement if (MOTO_SROM_BUG) lp->active = 0; using this macro indicates lp->active could be 8. If lp->active is 8 and the second comparison of this macro is false. lp->active will remain 8 in: lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].mc = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2; lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2; lp->phy[lp->active].mci = *p; However, the length of array lp->phy is 8, so array overflows can occur. To fix these possible array overflows, we first check lp->active and then return -EINVAL if it is greater or equal to ARRAY_SIZE(lp->phy) (i.e. 8).

queue Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2021-11-17 This series contains updates to i40e driver only. Eryk adds accounting for VLAN header in packet size when VF port VLAN is configured. He also fixes TC queue distribution when the user has changed queue counts as well as for configuration of VF ADQ which caused dropped packets. Michal adds tracking for when a VSI is being released to prevent null pointer dereference when managing filters. Karen ensures PF successfully initiates VF requested reset which could cause a call trace otherwise. Jedrzej moves validation of channel queue value earlier to prevent partial configuration when the value is invalid. Grzegorz corrects the reported error when adding filter fails. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The offset value is used in pointer math on skb->data. Since ipv6_skip_exthdr may return -1 the pointer to uh and th may not point to the actual udp and tcp headers and potentially overwrite other stuff. This is why I think this should be checked.

As reported in [1], e100 was no longer working for suspend/resume cycles. The previous commit mentioned in the fixes appears to have broken things and this attempts to practice best known methods for device power management and keep wake-up working while allowing suspend/resume to work. To do this, I reorder a little bit of code and fix the resume path to make sure the device is enabled.

The mlxsw driver calls to various devlink flash routines even before users can get any access to the devlink instance itself. For example, mlxsw_core_fw_rev_validate() one of such functions. __mlxsw_core_bus_device_register -> mlxsw_core_fw_rev_validate -> mlxsw_core_fw_flash -> mlxfw_firmware_flash -> mlxfw_status_notify -> devlink_flash_update_status_notify -> __devlink_flash_update_notify -> WARN_ON(...) It causes to the WARN_ON to trigger warning about devlink not registered.

This reverts commit d00e60ee. As reported by Guillaume in [1]: Enabling LPAE always enables CONFIG_ARCH_DMA_ADDR_T_64BIT in 32-bit systems, which breaks the bootup proceess when a ethernet driver is using page pool with PP_FLAG_DMA_MAP flag. As we were hoping we had no active consumers for such system when we removed the dma mapping support, and LPAE seems like a common feature for 32 bits system, so revert it. 1. https://www.spinics.net/lists/netdev/msg779890.html Fixes: d00e60ee ("page_pool: disable dma mapping support for 32-bit arch with 64-bit DMA") Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> Reported-by: "kernelci.org bot" <bot@kernelci.org> Tested-by: "kernelci.org bot" <bot@kernelci.org> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.

ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off; because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function returns.

Building allmodconfig shows errors in the gpu/drm/msm snapdragon drivers, because a COND() define is used there which conflicts with the COND() for PA-RISC assembly. Although the snapdragon driver isn't relevant for parisc, it is nevertheless compiled when CONFIG_COMPILE_TEST is defined. Move the COND() define and other PA-RISC mnemonics inside the #ifdef __ASSEMBLY__ part to avoid this conflict.
