commit 45cb6653b0c355fc1445a8069ba78a4ce8720511 upstream.

Return -EINVAL for authenc(hmac(sha1),cbc(aes)), authenc(hmac(sha256),cbc(aes)) and authenc(hmac(sha512),cbc(aes)) if the cipher length is not multiple of the AES block. This is to prevent an undefined device behaviour.

commit f19425641cb2572a33cb074d5e30283720bd4d22 upstream.

Only sockets will have the chan->data set to an actual sk, channels like A2MP would have its own data which would likely cause a crash when calling sk_filter, in order to fix this a new callback has been introduced so channels can implement their own filtering if necessary.

commit e1f13c879a7c21bd207dc6242455e8e3a1e88b40 upstream.

While finding usb endpoints in vmk80xx_find_usb_endpoints(), check if wMaxPacketSize = 0 for the endpoints found.

Some devices have isochronous endpoints that have wMaxPacketSize = 0 (as required by the USB-2 spec). However, since this doesn't apply here, wMaxPacketSize = 0 can be considered to be invalid.

commit 6cf87e5edd9944e1d3b6efd966ea401effc304ee upstream.

There exist many FT2232-based JTAG+UART adapter designs in which FT2232 Channel A is used for JTAG and Channel B is used for UART. The best way to handle them in Linux is to have the ftdi_sio driver create a ttyUSB device only for Channel B and not for Channel A: a ttyUSB device for Channel A would be bogus and will disappear as soon as the user runs OpenOCD or other applications that access Channel A for JTAG from userspace, causing undesirable noise for users. The ftdi_sio driver already has a dedicated quirk for such JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs to such adapters and adding these IDs to the driver with the ftdi_jtag_quirk applied.

Boutique hardware manufacturer Falconia Partners LLC has created a couple of JTAG+UART adapter designs (one buffered, one unbuffered) as part of FreeCalypso project, and this hardware is specifically made to be used with Linux hosts, with the intent that Channel A will be accessed only from userspace via appropriate applications, and that Channel B will be supported by the ftdi_sio kernel driver, presenting a standard ttyUSB device to userspace. Toward this end the hardware manufacturer will be programming FT2232 EEPROMs with custom USB IDs, specifically with the intent that these IDs will be recognized by the ftdi_sio driver with the ftdi_jtag_quirk applied.

commit c2bb80b8bdd04dfe32364b78b61b6a47f717af52 upstream.

With suitably crafted reiserfs image and mount command reiserfs will crash when trying to verify that XATTR_ROOT directory can be looked up in / as that recurses back to xattr code like:

Fix the problem by bailing from reiserfs_xattr_get() when xattrs are not yet initialized.
