[PATCH v2 2/2] drm/i915: Don't use BAR mappings for ring buffers with LLC

by John.C.Harrison＠Intel.com

From: Daniele Ceraolo Spurio <daniele.ceraolospurio(a)intel.com> Direction from hardware is that ring buffers should never be mapped via the BAR on systems with LLC. There are too many caching pitfalls due to the way BAR accesses are routed. So it is safest to just not use it.

[PATCH v2] f2fs: fix uninitialized skipped_gc_rwsem

by Yonggil Song

When f2fs skipped a gc round during victim migration, there was a bug which would skip all upcoming gc rounds unconditionally because skipped_gc_rwsem was not initialized. It fixes the bug by correctly initializing the skipped_gc_rwsem inside the gc loop.

[PATCH v2 1/2] thunderbolt: Adjust how NVM reading works

by Mario Limonciello

Some TBT3 devices have a hard time reliably responding to bit banging requests correctly when connected to AMD USB4 hosts running Linux. These problems are not reported in any other CM supported on AMD platforms, and comparing the Windows and Pre-OS implementations the Linux CM is the only one that utilizes bit banging to access the DROM. Other CM implementations access the DROM directly from the NVM instead of bit banging. Adjust the flow to use this method to fetch the NVM when the downstream device is Thunderbolt 3 and only use bit banging to access TBT 2 or TBT 1 devices. As the flow is modified, also remove the retry sequence that was introduced from commit f022ff7bf377 ("thunderbolt: Retry DROM read once if parsing fails") as it will not be necessary if the NVM is fetched this way. Cc: stable(a)vger.kernel.org Fixes: f022ff7bf377 ("thunderbolt: Retry DROM read once if parsing fails") Signed-off-by: Mario Limonciello <mario.limonciello(a)amd.com> --- v1->v2: * Update commit message to indicate which CMs are tested * Adjust flow to only fetch DROM from NVM on TBT3 and bit bang on TBT1/2 --- drivers/thunderbolt/eeprom.c | 145 +++++++++++++++++++---------------- 1 file changed, 80 insertions(+), 65 deletions(-) diff --git a/drivers/thunderbolt/eeprom.c b/drivers/thunderbolt/eeprom.c index c90d22f56d4e..d1be72b6afdb 100644 --- a/drivers/thunderbolt/eeprom.c +++ b/drivers/thunderbolt/eeprom.c @@ -416,7 +416,7 @@ static int tb_drom_parse_entries(struct tb_switch *sw, size_t header_size) if (pos + 1 == drom_size || pos + entry->len > drom_size || !entry->len) { tb_sw_warn(sw, "DROM buffer overrun\n"); - return -EILSEQ; + return -EIO; } switch (entry->type) { @@ -544,7 +544,37 @@ static int tb_drom_read_n(struct tb_switch *sw, u16 offset, u8 *val, return tb_eeprom_read_n(sw, offset, val, count); } -static int tb_drom_parse(struct tb_switch *sw) +static int tb_drom_bit_bang(struct tb_switch *sw, u16 *size) +{ + int res; + + res = tb_drom_read_n(sw, 14, (u8 *) size, 2); + if (res) + return res; + *size &= 0x3ff; + *size += TB_DROM_DATA_START; + tb_sw_dbg(sw, "reading drom (length: %#x)\n", *size); + if (*size < sizeof(struct tb_drom_header)) { + tb_sw_warn(sw, "drom too small, aborting\n"); + return -EIO; + } + + sw->drom = kzalloc(*size, GFP_KERNEL); + if (!sw->drom) + return -ENOMEM; + + res = tb_drom_read_n(sw, 0, sw->drom, *size); + if (res) + goto err; + + return 0; +err: + kfree(sw->drom); + sw->drom = NULL; + return res; +} + +static int tb_drom_parse_v1(struct tb_switch *sw) { const struct tb_drom_header *header = (const struct tb_drom_header *)sw->drom; @@ -555,7 +585,7 @@ static int tb_drom_parse(struct tb_switch *sw) tb_sw_warn(sw, "DROM UID CRC8 mismatch (expected: %#x, got: %#x)\n", header->uid_crc8, crc); - return -EILSEQ; + return -EIO; } if (!sw->uid) sw->uid = header->uid; @@ -589,6 +619,43 @@ static int usb4_drom_parse(struct tb_switch *sw) return tb_drom_parse_entries(sw, USB4_DROM_HEADER_SIZE); } +static int tb_drom_parse(struct tb_switch *sw, u16 *size) +{ + struct tb_drom_header *header = (void *) sw->drom; + int res; + + if (header->data_len + TB_DROM_DATA_START != *size) { + tb_sw_warn(sw, "drom size mismatch\n"); + goto err; + } + + tb_sw_dbg(sw, "DROM version: %d\n", header->device_rom_revision); + + switch (header->device_rom_revision) { + case 3: + res = usb4_drom_parse(sw); + break; + default: + tb_sw_warn(sw, "DROM device_rom_revision %#x unknown\n", + header->device_rom_revision); + fallthrough; + case 1: + res = tb_drom_parse_v1(sw); + break; + } + + if (res) { + tb_sw_warn(sw, "parsing DROM failed\n"); + goto err; + } + + return 0; +err: + kfree(sw->drom); + sw->drom = NULL; + return -EIO; +} + /** * tb_drom_read() - Copy DROM to sw->drom and parse it * @sw: Router whose DROM to read and parse @@ -602,8 +669,7 @@ static int usb4_drom_parse(struct tb_switch *sw) int tb_drom_read(struct tb_switch *sw) { u16 size; - struct tb_drom_header *header; - int res, retries = 1; + int res; if (sw->drom) return 0; @@ -614,11 +680,11 @@ int tb_drom_read(struct tb_switch *sw) * in a device property.

[PATCH AUTOSEL 6.1 01/24] Fix XFRM-I support for nested ESP tunnels

by Sasha Levin

From: Benedict Wong <benedictwong(a)google.com> [ Upstream commit b0355dbbf13c0052931dd14c38c789efed64d3de ] This change adds support for nested IPsec tunnels by ensuring that XFRM-I verifies existing policies before decapsulating a subsequent policies. Addtionally, this clears the secpath entries after policies are verified, ensuring that previous tunnels with no-longer-valid do not pollute subsequent policy checks. This is necessary especially for nested tunnels, as the IP addresses, protocol and ports may all change, thus not matching the previous policies. In order to ensure that packets match the relevant inbound templates, the xfrm_policy_check should be done before handing off to the inner XFRM protocol to decrypt and decapsulate. Notably, raw ESP/AH packets did not perform policy checks inherently, whereas all other encapsulated packets (UDP, TCP encapsulated) do policy checks after calling xfrm_input handling in the respective encapsulation layer.
