Merge tag 'ovl-fixes-5.19-rc7' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs into fs.idmapped.overlay.acl

Bring in Miklos' tree which contains the temporary fix for POSIX ACLs
with overlayfs on top of idmapped layers. We will add a proper fix on
top of it and then revert the temporary fix.

* Copyright IBM Corp. 2017, 2020
* Author(s): Harald Freudenberger
*
* The s390_arch_random_generate() function may be called from random.c
* in interrupt context. So this implementation does the best to be very
* fast. There is a buffer of random data which is asynchronously checked
* and filled by a workqueue thread.
* If there are enough bytes in the buffer the s390_arch_random_generate()
* just delivers these bytes. Otherwise false is returned until the
* worker thread refills the buffer.
* The worker fills the rng buffer by pulling fresh entropy from the
* high quality (but slow) true hardware random generator. This entropy
* is then spread over the buffer with an pseudo random generator PRNG.
* As the arch_get_random_seed_long() fetches 8 bytes and the calling
* function add_interrupt_randomness() counts this as 1 bit entropy the
* distribution needs to make sure there is in fact 1 bit entropy contained
* in 8 bytes of the buffer. The current values pull 32 byte entropy
* and scatter this into a 2048 byte buffer. So 8 byte in the buffer
* will contain 1 bit of entropy.
* The worker thread is rescheduled based on the charge level of the
* buffer but at least with 500 ms delay to avoid too much CPU consumption.
* So the max. amount of rng data delivered via arch_get_random_seed is
* limited to 4k bytes per second.

* Here follows the implementation of s390_arch_get_random_long().
*
* The random longs to be pulled by arch_get_random_long() are
* prepared in an 4K buffer which is filled from the NIST 800-90
* compliant s390 drbg. By default the random long buffer is refilled
* 256 times before the drbg itself needs a reseed. The reseed of the
* drbg is done with 32 bytes fetched from the high quality (but slow)
* trng which is assumed to deliver 100% entropy. So the 32 * 8 = 256
* bits of entropy are spread over 256 * 4KB = 1MB serving 131072
* arch_get_random_long() invocations before reseeded.
*
* How often the 4K random long buffer is refilled with the drbg
* before the drbg is reseeded can be adjusted. There is a module
* parameter 's390_arch_rnd_long_drbg_reseed' accessible via
* /sys/module/arch_random/parameters/rndlong_drbg_reseed
* or as kernel command line parameter
* arch_random.rndlong_drbg_reseed=<value>
* This parameter tells how often the drbg fills the 4K buffer before
* it is re-seeded by fresh entropy from the trng.
* A value of 16 results in reseeding the drbg at every 16 * 4 KB = 64
* KB with 32 bytes of fresh entropy pulled from the trng. So a value
* of 16 would result in 256 bits entropy per 64 KB.
* A value of 256 results in 1MB of drbg output before a reseed of the
* drbg is done. So this would spread the 256 bits of entropy among 1MB.
* Setting this parameter to 0 forces the reseed to take place every
* time the 4K buffer is depleted, so the entropy rises to 256 bits
* entropy per 4K or 0.5 bit entropy per arch_get_random_long(). With
* setting this parameter to negative values all this effort is
* disabled, arch_get_random long() returns false and thus indicating
* that the arch_get_random_long() feature is disabled at all.
