From b3f95490b9bec020314eb32016988ee262d52884 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 29 Oct 2017 19:32:10 +0100 Subject: kernel: generic: Add kernel 4.14 support This adds initial support for kernel 4.14 based on the patches for kernel 4.9. In the configuration I deactivated some of the new possible security features like: CONFIG_REFCOUNT_FULL CONFIG_SLAB_FREELIST_HARDENED CONFIG_SOFTLOCKUP_DETECTOR CONFIG_WARN_ALL_UNSEEDED_RANDOM And these overlay FS options are also deactivated: CONFIG_OVERLAY_FS_INDEX CONFIG_OVERLAY_FS_REDIRECT_DIR I activated this: CONFIG_FORTIFY_SOURCE CONFIG_POSIX_TIMERS CONFIG_SLAB_MERGE_DEFAULT CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED I am not sure if I did the porting correct for the following patches: target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch target/linux/generic/hack-4.14/220-gc_sections.patch target/linux/generic/hack-4.14/321-powerpc_crtsavres_prereq.patch target/linux/generic/pending-4.14/305-mips_module_reloc.patch target/linux/generic/pending-4.14/611-netfilter_match_bypass_default_table.patch target/linux/generic/pending-4.14/680-NET-skip-GRO-for-foreign-MAC-addresses.patch Signed-off-by: Hauke Mehrtens --- ...b-Remove-annoying-warning-about-bogus-URB.patch | 76 ++++++++++++++++++++++ 1 file changed, 76 insertions(+) create mode 100644 target/linux/generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch (limited to 'target/linux/generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch') diff --git a/target/linux/generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch b/target/linux/generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch new file mode 100644 index 0000000000..c14e679590 --- /dev/null +++ b/target/linux/generic/pending-4.14/821-usb-Remove-annoying-warning-about-bogus-URB.patch @@ -0,0 +1,76 @@ +From: Alexey Brodkin +Subject: usb: Remove annoying warning about bogus URB + +When ath9k-htc Wi-Fi dongle is used with generic OHCI controller +infinite stream of warnings appears in debug console like this: +-------------------------->8---------------------- +usb 1-1: new full-speed USB device number 2 using ohci-platform +usb 1-1: ath9k_htc: Firmware ath9k_htc/htc_9271-1.4.0.fw requested +usb 1-1: ath9k_htc: Transferred FW: ath9k_htc/htc_9271-1.4.0.fw, size: +51008 +------------[ cut here ]------------ +WARNING: CPU: 0 PID: 19 at drivers/usb/core/urb.c:449 +usb_submit_urb+0x1b4/0x498() +usb 1-1: BOGUS urb xfer, pipe 1 != type 3 +Modules linked in: +CPU: 0 PID: 19 Comm: kworker/0:1 Not tainted +4.4.0-rc4-00017-g00e2d79-dirty #3 +Workqueue: events request_firmware_work_func + +Stack Trace: + arc_unwind_core.constprop.1+0xa4/0x110 +---[ end trace 649ef8c342817fc2 ]--- +------------[ cut here ]------------ +WARNING: CPU: 0 PID: 19 at drivers/usb/core/urb.c:449 +usb_submit_urb+0x1b4/0x498() +usb 1-1: BOGUS urb xfer, pipe 1 != type 3 +Modules linked in: +CPU: 0 PID: 19 Comm: kworker/0:1 Tainted: G W +4.4.0-rc4-00017-g00e2d79-dirty #3 +Workqueue: events request_firmware_work_func + +Stack Trace: + arc_unwind_core.constprop.1+0xa4/0x110 +---[ end trace 649ef8c342817fc3 ]--- +------------[ cut here ]------------ +-------------------------->8---------------------- + +There're some discussions in mailing lists proposing to disable +that particular check alltogether and magically all seem to work +fine with muted warning. + +Anyways new thread on that regard could be found here: +http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html + +Let's see what comes out of that new discussion, hopefully patching +of generic USB stuff won't be required then. + +Signed-off-by: Alexey Brodkin +--- + drivers/usb/core/urb.c | 5 ----- + 1 file changed, 5 deletions(-) + +--- a/drivers/usb/core/urb.c ++++ b/drivers/usb/core/urb.c +@@ -326,9 +326,6 @@ EXPORT_SYMBOL_GPL(usb_unanchor_urb); + */ + int usb_submit_urb(struct urb *urb, gfp_t mem_flags) + { +- static int pipetypes[4] = { +- PIPE_CONTROL, PIPE_ISOCHRONOUS, PIPE_BULK, PIPE_INTERRUPT +- }; + int xfertype, max; + struct usb_device *dev; + struct usb_host_endpoint *ep; +@@ -443,11 +440,6 @@ int usb_submit_urb(struct urb *urb, gfp_ + * cause problems in HCDs if they get it wrong. + */ + +- /* Check that the pipe's type matches the endpoint's type */ +- if (usb_pipetype(urb->pipe) != pipetypes[xfertype]) +- dev_WARN(&dev->dev, "BOGUS urb xfer, pipe %x != type %x\n", +- usb_pipetype(urb->pipe), pipetypes[xfertype]); +- + /* Check against a simple/standard policy */ + allowed = (URB_NO_TRANSFER_DMA_MAP | URB_NO_INTERRUPT | URB_DIR_MASK | + URB_FREE_BUFFER); -- cgit v1.2.3
