[PATCH 2/2] KEYS: asymmetric: properly validate hash_algo and encoding

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> It is insecure to allow arbitrary hash algorithms and signature encodings to be used with arbitrary signature algorithms. Notably, ECDSA, ECRDSA, and SM2 all sign/verify raw hash values and don't disambiguate between different hash algorithms like RSA PKCS#1 v1.5 padding does. Therefore, they need to be restricted to certain sets of hash algorithms (ideally just one, but in practice small sets are used). Additionally, the encoding is an integral part of modern signature algorithms, and is not supposed to vary. Therefore, tighten the checks of hash_algo and encoding done by software_key_determine_akcipher(). Also rearrange the parameters to software_key_determine_akcipher() to put the public_key first, as this is the most important parameter and it often determines everything else. Fixes: 299f561a6693 ("x509: Add support for parsing x509 certs with ECDSA keys") Fixes: 215525639631 ("X.509: support OSCCA SM2-with-SM3 certificate verification") Fixes: 0d7a78643f69 ("crypto: ecrdsa - add EC-RDSA (GOST 34.10) algorithm") Cc: stable(a)vger.kernel.org Signed-off-by: Eric Biggers <ebiggers(a)google.com> --- crypto/asymmetric_keys/public_key.c | 111 +++++++++++++++++++--------- 1 file changed, 76 insertions(+), 35 deletions(-) diff --git a/crypto/asymmetric_keys/public_key.c b/crypto/asymmetric_keys/public_key.c index aba7113d86c76..a603ee8afdb8d 100644 --- a/crypto/asymmetric_keys/public_key.c +++ b/crypto/asymmetric_keys/public_key.c @@ -60,39 +60,83 @@ static void public_key_destroy(void *payload0, void *payload3) } /* - * Determine the crypto algorithm name. + * Given a public_key, and an encoding and hash_algo to be used for signing + * and/or verification with that key, determine the name of the corresponding + * akcipher algorithm.

patch "sc16is7xx: Fix for incorrect data being transmitted" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled sc16is7xx: Fix for incorrect data being transmitted to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-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 eebb0f4e894f1e9577a56b337693d1051dd6ebfd Mon Sep 17 00:00:00 2001 From: Phil Elwell <phil(a)raspberrypi.com> Date: Wed, 16 Feb 2022 16:08:02 +0000 Subject: sc16is7xx: Fix for incorrect data being transmitted UART drivers are meant to use the port spinlock within certain methods, to protect against reentrancy. The sc16is7xx driver does very little locking, presumably because when added it triggers "scheduling while atomic" errors. This is due to the use of mutexes within the regmap abstraction layer, and the mutex implementation's habit of sleeping the current thread while waiting for access. Unfortunately this lack of interlocking can lead to corruption of outbound data, which occurs when the buffer used for I2C transmission is used simultaneously by two threads - a work queue thread running sc16is7xx_tx_proc, and an IRQ thread in sc16is7xx_port_irq, both of which can call sc16is7xx_handle_tx. An earlier patch added efr_lock, a mutex that controls access to the EFR register. This mutex is already claimed in the IRQ handler, and all that is required is to claim the same mutex in sc16is7xx_tx_proc.

Here I agree with Loic. An interface that is exported through the WWAN subsystem should be common enough for WWAN devices. For a firmware crash dump collection, there are better solutions like devcoredump as already pointed out by Loic. The firmware update function can be implemented using the devlink firmware flashing API. You could see the use of both APIs in the IOSM driver. If none of these interfaces can be used to utilize the SAHARA functionality, then, as Loic has already pointed out, such an interface should probably go to the debugfs. But I suggest to implement the firmware management functionality using the generic kernel API. This will save time for end users, distro maintainers and probably for modem vendor support too. -- Sergey
