2020-12-14libceph: introduce connection modes and ms_mode optionIlya Dryomov
msgr2 supports two connection modes: crc (plain) and secure (on-wire encryption). Connection mode is picked by server based on input from client. Introduce ms_mode option: ms_mode=legacy - msgr1 (default) ms_mode=crc - crc mode, if denied fail ms_mode=secure - secure mode, if denied fail ms_mode=prefer-crc - crc mode, if denied agree to secure mode ms_mode=prefer-secure - secure mode, if denied agree to crc mode ms_mode affects all connections, we don't separate connections to mons like it's done in userspace with ms_client_mode vs ms_mon_client_mode. For now the default is legacy, to be flipped to prefer-crc after some time. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14libceph, rbd: ignore addr->type while comparing in some casesIlya Dryomov
For libceph, this ensures that libceph instance sharing (share option) continues to work. For rbd, this avoids blocklisting alive lock owners (locker addr is always LEGACY, while watcher addr is ANY in nautilus). Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14libceph, ceph: get and handle cluster maps with addrvecsIlya Dryomov
In preparation for msgr2, make the cluster send us maps with addrvecs including both LEGACY and MSGR2 addrs instead of a single LEGACY addr. This means advertising support for SERVER_NAUTILUS and also some older features: SERVER_MIMIC, MONENC and MONNAMES. MONNAMES and MONENC are actually pre-argonaut, we just never updated ceph_monmap_decode() for them. Decoding is unconditional, see commit 23c625ce3065 ("libceph: assume argonaut on the server side"). SERVER_MIMIC doesn't bear any meaning for the kernel client. Since ceph_decode_entity_addrvec() is guarded by encoding version checks (and in msgr2 case it is guarded implicitly by the fact that server is speaking msgr2), we assume MSG_ADDR2 for it.

2020-12-14libceph: amend cephx init_protocol() and build_request()Ilya Dryomov
In msgr2, initial authentication happens with an exchange of msgr2 control frames -- MAuth message and struct ceph_mon_request_header aren't used. Make that optional. Stop reporting cephx protocol as "x". Use "cephx" instead. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14libceph, ceph: incorporate nautilus cephx changesIlya Dryomov
- request service tickets together with auth ticket. Currently we get auth ticket via CEPHX_GET_AUTH_SESSION_KEY op and then request service tickets via CEPHX_GET_PRINCIPAL_SESSION_KEY op in a separate message. Since nautilus, desired service tickets are shared togther with auth ticket in CEPHX_GET_AUTH_SESSION_KEY reply. - propagate session key and connection secret, if any. In preparation for msgr2, update handle_reply() and verify_authorizer_reply() auth ops to propagate session key and connection secret. Since nautilus, if secure mode is negotiated, connection secret is shared either in CEPHX_GET_AUTH_SESSION_KEY reply (for mons) or in a final authorizer reply (for osds and mdses).

2020-12-14libceph: move msgr1 protocol implementation to its own fileIlya Dryomov
A pure move, no other changes. Note that ceph_tcp_recv{msg,page}() and ceph_tcp_send{msg,page}() helpers are also moved. msgr2 will bring its own, more efficient, variants based on iov_iter. Switching msgr1 to them was considered but decided against to avoid subtle regressions. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14libceph: separate msgr1 protocol implementationIlya Dryomov
In preparation for msgr2, define internal messenger <-> protocol interface (as opposed to external messenger <-> client interface, which is struct ceph_connection_operations) consisting of try_read(), try_write(), revoke(), revoke_incoming(), opened(), reset_session() and reset_protocol() ops. The semantics are exactly the same as they are now. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2020-12-14libceph: rename and export con->state statesIlya Dryomov
In preparation for msgr2, rename msgr1 specific states and move the defines to the header file. Also drop state transition comments. They don't cover all possible transitions (e.g. NEGOTIATING -> STANDBY, etc) and currently do more harm than good. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14libceph: make con->state an intIlya Dryomov

2020-12-14libceph: lower exponential backoff delayIlya Dryomov
The current setting allows the backoff to climb up to 5 minutes. This is too high -- it becomes hard to tell whether the client is stuck on something or just in backoff. In userspace, ms_max_backoff is defaulted to 15 seconds. Let's do the same. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-14ceph: implement updated ceph_mds_request_head structureJeff Layton
When we added the btime feature in mainline ceph, we had to extend struct ceph_mds_request_args so that it could be set. Implement the same in the kernel client. Rename ceph_mds_request_head with a _old extension, and a union ceph_mds_request_args_ext to allow for the extended size of the new header format. Add the appropriate code to handle both formats in struct create_request_message and key the behavior on whether the peer supports CEPH_FEATURE_FS_BTIME. The gid_list field in the payload is now populated from the saved credential. For now, we don't add any support for setting the btime via setattr, but this does enable us to add that in the future.

2020-12-14ceph: add new RECOVER mount_state when recovering sessionJeff Layton
When recovering a session (a'la recover_session=clean), we want to do all of the operations that we do on a forced umount, but changing the mount state to SHUTDOWN is can cause queued MDS requests to fail when the session comes back. Most of those can idle until the session is recovered in this situation. Reserve SHUTDOWN state for forced umount, and make a new RECOVER state for the forced reconnect situation. Change several tests for equality with SHUTDOWN to test for that or RECOVER.

2020-12-14efi: ia64: disable the capsule loaderArd Biesheuvel
EFI capsule loading is a feature that was introduced into EFI long after its initial introduction on Itanium, and it is highly unlikely that IA64 systems are receiving firmware updates in the first place, let alone using EFI capsules. So let's disable capsule support altogether on IA64. This fixes a build error on IA64 due to a recent change that added an unconditional include of asm/efi.h, which IA64 does not provide. While at it, tweak the make rules a bit so that the EFI capsule component that is always builtin (even if the EFI capsule loader itself is built as a module) is omitted for all architectures if the module is not enabled in the build.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.11 There's a lot of changes here but mostly cleanups and driver specific things, the most user visible change is the support for boot time selection of Intel DSP firmware which will make it easier for people to move over to the preferred modern implementations in distros and other large scale deployments. This also includes a merge of the new auxillary bus which was done in anticipation of use by the Intel DSP drivers which didn't quite make it. - Lots more cleanups and simplifications from Morimoto-san. - Support for some basic DPCM systems in the audio graph card from Sameer Pujar. - Remove some old pre-DT Freescale drivers for platforms that are now DT only. - Move selection of which Intel DSP implementation to use to boot time rather than requiring it to be selected at build time. - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715, Qualcomm SM8250 and simple GPIO based muxes.
2020-12-14vfs: move cap_convert_nscap() call into vfs_setxattr()Miklos Szeredi
cap_convert_nscap() does permission checking as well as conversion of the xattr value conditionally based on fs's user-ns. This is needed by overlayfs and probably other layered fs (ecryptfs) and is what vfs_foo() is supposed to do anyway.

2020-12-11x86,swiotlb: Adjust SWIOTLB bounce buffer size for SEV guestsAshish Kalra
For SEV, all DMA to and from guest has to use shared (un-encrypted) pages. SEV uses SWIOTLB to make this happen without requiring changes to device drivers. However, depending on the workload being run, the default 64MB of it might not be enough and it may run out of buffers to use for DMA, resulting in I/O errors and/or performance degradation for high I/O workloads. Adjust the default size of SWIOTLB for SEV guests using a percentage of the total memory available to guest for the SWIOTLB buffers. Adds a new sev_setup_arch() function which is invoked from setup_arch() and it calls into a new swiotlb generic code function swiotlb_adjust_size() to do the SWIOTLB buffer adjustment. v5 fixed build errors and warnings as Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Ashish Kalra <ashish.kalra@amd.com> Co-developed-by: Borislav Petkov <bp@suse.de> Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux Pull devfreq updates for 5.11 from Chanwoo Choi: 1. Update devfreq core - Add new devfreq_frequency tracepoint to show the frequency change information. - Add governor feature flag. The devfreq governor is able to set the specific flag in order to support a non-common feature. For example, if the governor supports the 'immutable' feature, don't allow user space to change the governor via sysfs. - Add governor sysfs attribute flag for each sysfs file. Prior to that the devfreq subsystem allowed all of the sysfs files to be accessed regardless of the governor type. But some sysfs fils are not supported by specific devfreq governors. In order to only allow the sysfs files supported by the governor to be accessed, clarify the access permissions of sysfs attributes according to the governor. When adding the devfreq governor, specify the available attribute information by using DEVFREQ_GOV_ATTR_* symbols. The user can read or write the sysfs attributes in accordance to the specified access permissions. - Clean-up the code to reduce duplication for the devfreq tracepoint and to remove redundant governor_name field from struct devfreq. 2. Update exynos-bus.c devfreq driver - Add interconnect API support to the Samsung Exynos Bus Frequency driver, exynos-bus.c. Complementing the devfreq driver with interconnect functionality allows to ensure that the QoS requirements regarding devices accessing the system memory (e.g. video processing devices) will be met and allows to avoid issues like DMA underrun. 3. Update tegra devfreq driver - Add interconnect support and OPP interface to tegra30-devfreq.c. Also, it is to guarantee the QoS requirement of some devices like the display controller. - Move tegra20-devfreq.c from drivers/devfreq/ into drivers/memory/tegra/ in order to use the more proper monitoring feature such as EMC_STAT which is located in drivers/memory/tegra/. - Separate the configuration information for different SoCs in tegra30-devfrqe.c. The tegra30-devfreq.c had been supporting both tegra30-actmon and tegra124-actmon devices. In order to use the more correct configuration data, separate them. - Use dev_err_probe() to handle the deferred probe error in tegra30-devfreq.c. 4.
