Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b

Add options to strictly validate messages and dump messages,
sometimes perhaps validating dump messages non-strictly may
be required, so add an option for that as well.
Since none of this can really be applied to existing commands,
set the options everwhere using the following spatch:
@@
identifier ops;
expression X;
@@
struct genl_ops ops[] = {
...,
{
.cmd = X,
+ .validate = GENL_DONT_VALIDATE_STRICT | GENL_DONT_VALIDATE_DUMP,

For new commands one should just not copy the .validate 'opt-out'
flags and thus get strict validation.

The flags field in 'struct shash_desc' never actually does anything.
The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP.
However, no shash algorithm ever sleeps, making this flag a no-op.
With this being the case, inevitably some users who can't sleep wrongly
pass MAY_SLEEP. These would all need to be fixed if any shash algorithm
actually started sleeping. For example, the shash_ahash_*() functions,
which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP
from the ahash API to the shash API. However, the shash functions are
called under kmap_atomic(), so actually they're assumed to never sleep.
Even if it turns out that some users do need preemption points while
hashing large buffers, we could easily provide a helper function
crypto_shash_update_large() which divides the data into smaller chunks
and calls crypto_shash_update() and cond_resched() for each chunk. It's
not necessary to have a flag in 'struct shash_desc', nor is it necessary
to make individual shash algorithms aware of this at all.
Therefore, remove shash_desc::flags, and document that the
crypto_shash_*() functions can be called from any context.

Currently the iSCSI target driver sends a CHECK CONDITION code back to the
initiator if the immediate data buffer is too large but it does not discard
that immediate data buffer. The result is that the iSCSI target driver
attempts to parse the immediate data itself as iSCSI PDUs and that all
further iSCSI communication fails. Fix this by receiving and discarding too
large immediate data buffers.

Since target_alloc_sgl() and iscsit_allocate_iovecs() allocate buffer space
for se_cmd.data_length bytes and since that number can be smaller than the
iSCSI Expected Data Transfer Length (EDTL), ensure that the iSCSI target
driver does not attempt to receive more bytes than what fits in the receive
buffer. Always receive the full immediate data buffer such that the iSCSI
target driver does not attempt to parse immediate data as an iSCSI PDU.
Note: the current code base only calls iscsit_get_dataout() if the size of
the immediate data buffer does not exceed the buffer size derived from the
SCSI CDB. See also target_cmd_size_check().

If an initiator submits more immediate data than the size derived from the
SCSI CDB, do not send any R2T to the initiator. This scenario is triggered
by the libiscsi test ALL.iSCSIResiduals.WriteVerify16Residuals if the iSCSI
target driver is modified to discard too large immediate data buffers
instead of trying to parse these as an iSCSI PDU. This patch avoids that a
negative xfer_len value is passed to iscsit_add_r2t_to_list() if too large
immediate data buffers are handled correctly.

Certain behavior of an initiator can cause the target driver to send both a
reject and a SCSI response. If that happens two target_put_sess_cmd() calls
will occur without the command having been removed from conn_cmd_list. In
other words, conn_cmd_list will get corrupted once the freed memory is
reused. Although the Linux kernel can detect list corruption if list
debugging is enabled, in this case the context in which list corruption is
detected is not related to the context that caused list corruption. Hence
add WARN_ON() statements that report the context that is causing list
corruption.

Since maxattr is common, the policy can't really differ sanely,
so make it common as well.
The only user that did in fact manage to make a non-common policy
is taskstats, which has to be really careful about it (since it's
still using a common maxattr!). This is no longer supported, but
we can fake it using pre_doit.
This reduces the size of e.g. nl80211.o (which has lots of commands):
text data bss dec hex filename
398745 14323 2240 415308 6564c net/wireless/nl80211.o (before)
397913 14331 2240 414484 65314 net/wireless/nl80211.o (after)
--------------------------------
-832 +8 0 -824
Which is obviously just 8 bytes for each command, and an added 8
bytes for the new policy pointer. I'm not sure why the ops list is
counted as .text though.
Most of the code transformations were done using the following spatch:
@ops@
identifier OPS;
expression POLICY;
@@
struct genl_ops OPS[] = {
...,
{
- .policy = POLICY,
},
...
};
@@
identifier ops.OPS;
expression ops.POLICY;
identifier fam;
expression M;
@@
struct genl_family fam = {
.ops = OPS,
.maxattr = M,
+ .policy = POLICY,
...
};
This also gets rid of devlink_nl_cmd_region_read_dumpit() accessing
the cb->data as ops, which we want to change in a later genl patch.
