There have been several attempts to fix serious problems
in the compat handling in megasas_mgmt_compat_ioctl_fw(),
and it also uses the compat_alloc_user_space() function.
Folding the compat handling into the regular ioctl

avoids some of th
It sounds unwise to let user space pass an unchecked 32-bit
offset into a kernel structure in an ioctl. This is an unsigned
variable, so checking the upper bound for the size of the structure
it points into is sufficient to avoid data corruption, but as
the pointer might also be unaligned, it has t

Previously it was not possible to make a distinction between plain TCP
sockets and MPTCP subflow sockets on the BPF_PROG_TYPE_SOCK_OPS hook.
This patch series now enables a fine control of subflow sockets. In its
current state, it allows to put different sockopt on each subflow from a
same MPTCP c
is_mptcp is a field from struct tcp_sock used to indicate that the
current tcp_sock is part of the MPTCP protocol.
In this protocol, a first socket (mptcp_sock) is created with
sk_protocol set to IPPROTO_MPTCP (=262) for control purpose but it
isn't directly on the wire. This is the role of the su
This patch adds verifier side tests for the new bpf_mptcp_sock() helper.
Here are the new tests :
- NULL bpf_sock is correctly handled
- We cannot access a field from bpf_mptcp_sock if the latter is NULL
- We can access a field from bpf_mptcp_sock if the latter is not NULL
- We cannot modify a fie
In order to precisely identify the parent MPTCP connection of a subflow,
it is required to access the mptcp_sock's token which uniquely identify a
MPTCP connection.
This patch adds a new structure 'bpf_mptcp_sock' exposing the 'token' field
of the 'mptcp_sock' extracted from a subflow's 'tcp_sock'
This patch adds a base for MPTCP specific tests.
It is currently limited to the is_mptcp field in case of plain TCP
connection because for the moment there is no easy way to get the subflow
sk from a msk in userspace. This implies that we cannot lookup the

It has been observed that the kernel sockets created for the subflows

That's because the additional subflows are created by kernel workers.

The use of compat_alloc_user_space() can be easily replaced by
handling compat arguments in the regular handler, and this will
make it work for big-endian kernels as well, which at the moment

Rename some functions and variables in advance, to make the next patch
looks more clear. The details are as follows:
1. rename dw_apb_ictl_handler() to dw_apb_ictl_handle_irq_cascaded().
2. change (1 << hwirq) to BIT(hwirq).
In function dw_apb_ictl_init():

Hi Zhiqiang,
So the alternative solution seems to correct the PCIe enumeration, I
will submit
a patch to let the first access only read the Vendor ID.
Please put me on CC of that patch.
Thanks,

When someone attacks the service provider, it creates connection,
authenticates. Then it requests key size of one byte and it identifies
the key with brute force methods.
After l2cap info req/resp exchange is complete. the attacker sends l2cap
connect with specific PSM.
In above procedure, there

Please ignore this patch, the code need to rewrite.

We're documented that we do. Lots of code relies on that.
