patch "USB: net2280: Fix erroneous synchronization change" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: net2280: Fix erroneous synchronization change to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From dec3c23c9aa1815f07d98ae0375b4cbc10971e13 Mon Sep 17 00:00:00 2001 From: Alan Stern <stern(a)rowland.harvard.edu> Date: Wed, 8 Aug 2018 11:20:39 -0400 Subject: USB: net2280: Fix erroneous synchronization change Commit f16443a034c7 ("USB: gadgetfs, dummy-hcd, net2280: fix locking for callbacks") was based on a serious misunderstanding. It introduced regressions into both the dummy-hcd and net2280 drivers. The problem in dummy-hcd was fixed by commit 7dbd8f4cabd9 ("USB: dummy-hcd: Fix erroneous synchronization change"), but the problem in net2280 remains. Namely: the ->disconnect(), ->suspend(), ->resume(), and ->reset() callbacks must be invoked without the private lock held; otherwise a deadlock will occur when the callback routine tries to interact with the UDC driver. This patch largely is a reversion of the relevant parts of f16443a034c7. It also drops the private lock around the calls to ->suspend() and ->resume() (something the earlier patch forgot to do). This is safe from races with device interrupts because it occurs within the interrupt handler. Finally, the patch changes where the ->disconnect() callback is invoked when net2280_pullup() turns the pullup off. Rather than making the callback from within stop_activity() at a time when dropping the private lock could be unsafe, the callback is moved to a point after the lock has already been dropped.

The next day, Eric Dumazet, the author of the first patch, proposed a second one which "simply" reverts this commit: 29869d66870a715177bfb505f66a7e0e8bcc89c3 (tcp: Revert "tcp: tcp_probe: use spin_lock_bh()") You can find the discussions about this patch here, including a question from Eric not being sure why it is not needed: https://patchwork.ozlabs.org/patch/730560/ After having applied this patch (the reverted commit - 29869d66870a) on the v4.9 tree, I confirm I no longer have the warning mentioned at the beginning of this email. I don't think many people are still using tcp probe -- recently removed in v4.16 -- but it could be nice if someone could backport the commit 29869d66870a in v4.9.y tree to avoid extra warnings. Again, thank you for your very nice work!

+ mm-shmem-correctly-annotate-new-inodes-for-lockdep.patch added to -mm tree

As a result, on x86, a failure to duplicate the LDT (e.g., due to memory allocation error), would leave the duplicated memory mapping in an inconsistent state. Fix by regarding the return value, as it was before the change.

[PATCH v2 2/8] mtd: maps: gpio-addr-flash: Fix ioremapped size

We should only iomap the area of the chip that is memory mapped. Otherwise we could be mapping devices beyond the memory space or that belong to other devices.

patch "USB: serial: ti_usb_3410_5052: fix array underflow in completion" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: ti_usb_3410_5052: fix array underflow in completion to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 5dfdd24eb3d39d815bc952ae98128e967c9bba49 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Tue, 21 Aug 2018 11:59:53 +0200 Subject: USB: serial: ti_usb_3410_5052: fix array underflow in completion handler Similarly to a recently reported bug in io_ti, a malicious USB device could set port_number to a negative value and we would underflow the port array in the interrupt completion handler.

[PATCH] tpm: fix response size validation in tpm_get_random()

by Jarkko Sakkinen

When checking whether the response is large enough to be able to contain the received random bytes in tpm_get_random() and tpm2_get_random(), they fail to take account the header size, which should be added to the minimum size. This commit fixes this issue.

One command is used to set up new endpoints, free old endpoints, check bandwidth, and run the new endpoints. All this is done by xHC when usb core asks the hcd to check for available bandwidth. At this point usb core has not yet flushed the old endpoints, which will cause use-after-free issues in xhci driver as queued URBs are cancelled on a re-allocated endpoint. To resolve this add a call to usb_disable_interface() which will flush the endpoints before calling usb_hcd_alloc_bandwidth() Additional checks in xhci driver will also be implemented to gracefully handle stale URB cancel on freed and re-allocated endpoints Cc: <stable(a)vger.kernel.org> Reported-by: Sudip Mukherjee <sudipm.mukherjee(a)gmail.com> Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Acked-by: Alan Stern <stern(a)rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/usb/core/message.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/drivers/usb/core/message.c b/drivers/usb/core/message.c index 228672f2c4a1..bfa5eda0cc26 100644 --- a/drivers/usb/core/message.c +++ b/drivers/usb/core/message.c @@ -1341,6 +1341,11 @@ void usb_enable_interface(struct usb_device *dev, * is submitted that needs that bandwidth.
