2020-07-03gfs2: When freezing gfs2, use GL_EXACT and not GL_NOCACHEBob Peterson2-11/+9
Before this patch, the freeze code in gfs2 specified GL_NOCACHE in several places. That's wrong because we always want to know the state of whether the file system is frozen. There was also a problem with freeze/thaw transitioning the glock from frozen (EX) to thawed (SH) because gfs2 will normally grant glocks in EX to processes that request it in SH mode, unless GL_EXACT is specified. Therefore, the freeze/thaw code, which tried to reacquire the glock in SH mode would get the glock in EX mode, and miss the transition from EX to SH. That made it think the thaw had completed normally, but since the glock was still cached in EX, other nodes could not freeze again. This patch removes the GL_NOCACHE flag to allow the freeze glock to be cached. It also adds the GL_EXACT flag so the glock is fully transitioned from EX to SH, thereby allowing future freeze operations. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-07-03gfs2: read-only mounts should grab the sd_freeze_gl glockBob Peterson1-1/+11
Before this patch, only read-write mounts would grab the freeze glock in read-only mode, as part of gfs2_make_fs_rw. So the freeze glock was never initialized. That meant requests to freeze, which request the glock in EX, were granted without any state transition. That meant you could mount a gfs2 file system, which is currently frozen on a different cluster node, in read-only mode. This patch makes read-only mounts lock the freeze glock in SH mode, which will block for file systems that are frozen on another node. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-07-03gfs2: freeze should work on read-only mountsBob Peterson1-4/+6
Before this patch, function freeze_go_sync, called when promoting the freeze glock, was testing for the SDF_JOURNAL_LIVE superblock flag. That's only set for read-write mounts. Read-only mounts don't use a journal, so the bit is never set, so the freeze never happened. This patch removes the check for SDF_JOURNAL_LIVE for freeze requests but still checks it when deciding whether to flush a journal. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
2020-07-03gfs2: eliminate GIF_ORDERED in favor of list_emptyBob Peterson4-9/+12
In several places, we used the GIF_ORDERED inode flag to determine if an inode was on the ordered writes list. However, since we always held the sd_ordered_lock spin_lock during the manipulation, we can just as easily check list_empty(&ip->i_ordered) instead. This allows us to keep more than one ordered writes list to make journal writing improvements. This patch eliminates GIF_ORDERED in favor of checking list_empty.

Edward Cree says: ==================== sfc: prerequisites for EF100 driver, part 3 Continuing on from [1] and [2], this series assembles the last pieces of the common codebase that will be used by the forthcoming EF100 driver. Patch #1 also adds a minor feature to EF10 (setting MTU on VFs) since EF10 supports the same MCDI extension which that feature will use on EF100. Patches #5 & #7, while they should have no externally-visible effect on driver functionality, change how that functionality is implemented and how the driver represents TXQ configuration internally, so are not mere cleanup/refactoring like most of these prerequisites have (from the perspective of the existing sfc driver) been. Changes in v2: * Patch #1: use efx_mcdi_set_mtu() directly, instead of as a fallback, in the mtu_only case (Jakub) * Patch #3: fix symbol collision in non-modular builds by renaming interrupt_mode to efx_interrupt_mode (kernel test robot) * Patch #6: check for failure of netif_set_real_num_[tr]x_queues (Jakub) * Patch #12: cleaner solution for ethtool drvinfo (Jakub, David) [1]: https://lore.kernel.org/netdev/20200629.173812.1532344417590172093.davem@davemloft.net/T/ [2]: https://lore.kernel.org/netdev/20200630.130923.402514193016248355.davem@davemloft.net/T/ ==================== Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-07-03sfc: assign TXQs without gapsEdward Cree10-72/+58
Since we only allocate VIs for the number of TXQs we actually need, we cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and thus overruns the driver's VI allocations, causing the firmware to reject the MC_CMD_INIT_TXQ based on INSTANCE. Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL (tx_queue->label); the former is allocated starting from 0 in efx_set_channels(), while the latter is simply the txq type (index in channel->tx_queue array). To simplify things, rather than changing tx_queues_per_channel after setting up TXQs, make Siena always probe its HIGHPRI queues at start of day, rather than deferring it until tc mqprio enables them.

2020-07-03sfc: make tx_queues_per_channel variable at runtimeEdward Cree6-31/+30
Siena needs four TX queues (csum * highpri), EF10 needs two (csum), and EF100 only needs one (as checksumming is controlled entirely by the transmit descriptor). Rather than having various bits of ad-hoc code to decide which queues to set up etc., put the knowledge of how many TXQs a channel has in one place.

2020-07-03sfc: move modparam 'rss_cpus' out of common channel codeEdward Cree3-3/+5
Instead of exposing this old module parameter on the new driver (thus having to keep it forever after for compatibility), let's confine it to the old one; if we find later that we need the feature, we ought to support it properly, with ethtool set-channels.

2020-07-03sfc: move modparam 'interrupt_mode' out of common channel codeEdward Cree3-5/+8
EF100 only supports MSI-X, so there's no need for the new driver to expose this old module parameter. Since it's now visible to the linker, we have to rename it internally to efx_interrupt_mode to avoid symbol collisions in non-modular builds.

2020-07-03sfc: remove max_interrupt_modeEdward Cree4-12/+0
All NICs supported by this driver are capable of MSI-X interrupts (only Falcon A1 wasn't, and that's now hived off into its own driver), so no need for a nic-type parameter. Besides, the code that checked it was buggy anyway (the following assignment that checked min_interrupt_mode overrode it). Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.

2020-07-03sfc: support setting MTU even if not privileged to configure MAC fullyEdward Cree7-23/+16
Unprivileged functions (such as VFs) may set their MTU by use of the 'control' field of MC_CMD_SET_MAC_EXT, as used in efx_mcdi_set_mtu(). If calling efx_ef10_mac_reconfigure() from efx_change_mtu(), and the NIC supports the above (SET_MAC_ENHANCED capability), use it rather than efx_mcdi_set_mac().

2020-07-03Merge branch 'net-ipa-simplify-endpoint-programming'David S. Miller1-91/+99
Alex Elder says: ==================== net: ipa: simplify endpoint programming Add tests to functions so they don't update undefined endpoint registers, rather than requiring the caller to avoid calling them. Move the call to a workaround function required when suspending inside the function that puts an endpoint into suspend mode. This requires moving a few functions (which are otherwise unchanged). Then simplify ipa_endpoint_program() to call essentially all endpoint register update functions unconditionally. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-03net: ipa: simplify ipa_endpoint_program()Alex Elder1-11/+20
Have functions that write endpoint configuration registers return immediately if they are not valid for the direction of transfer for the endpoint. This allows most of the calls in ipa_endpoint_program() to be made unconditionally. Reorder the register writes to match the order of their definition (based on offset).
