8 months agoMake it explicit that the EC_KEY setters don't check things
tb [Fri, 16 Feb 2024 06:09:36 +0000 (06:09 +0000)]
Make it explicit that the EC_KEY setters don't check things

While EC_POINT_set_affine_coordinates() checks that the resulting point
is on the elliptic curve, this is only necessary, but not sufficient, to
ensure that the point can serve as a valid public key. For example, this
does not check for normalized coordinates or exclude that it is zero (the
point at infinity). Such checks, and more, are performed by the similarly
named EC_KEY_set_public_key_affine_coordinates().

This kind of makes sense from the mathematical standpoint as an elliptic
curve point isn't a priori a public key, even if you are not going to use
libcrypto for actual mathematics (or anything really) unless you like pain.
In a cryptographic library such differences are more of a hazard than a
help.

This is exacerbated by the fact that EC_KEY_set_public_key() does almost
no checking (it only checks that the point's EC_POINT method matches the
one of group set of the EC_KEY, which is far from enough). The API expects
that you call EC_KEY_check_key() on your own. This is kind of confusing
since EC_KEY_set_public_key_affine_coordinates() does that for you.

Unfortunately, adding sanity checks to EC_KEY_set_public_key() isn't easy
since it's going to penalize those who already check. Caching the result
of a check is dangerous and fragile if there are a million ways of fiddling
with an EC_KEY.

While the elliptic curve code is really bad, its documentation is worse
(another thing that applies to OpenSSL in general). Try to help that a
little bit by making it more explicit that you are supposed to call
EC_KEY_check_key() after using lower-level EC_KEY setters. Also make it
clearer that the setters copy the data, they don't take ownership (which
isn't obvious from the naming).

If OpenSSL 3 got one thing kind of right, it was to deprecate the EC_KEY
and EC_POINT APIs. But if you are going to deprecate something, you should
either be prepared to remove it or have a reasonable replacement...

Analyse header layout in ether_extract_headers().

Several drivers need IPv4 header length and TCP offset for checksum
offload, TSO and LRO.  Accessing these fields directly caused crashes
on sparc64 due to misaligned access.  It cannot be guaranteed that
IP and TCP header is 4 byte aligned in driver level.  Also gcc 4.2.1
assumes that bit fields can be accessed with 32 bit load instructions.

Use memcpy() in ether_extract_headers() to get the bits from IPv4
and TCP header and store the header length in struct ether_extracted.
From there network drivers can esily use it without caring about
alignment and bit shift.  Do some sanity checks with the length
values to prevent that invalid values from evil packets get stored
into hardware registers.  If check fails, clear the pointer to the
header to hide it from the driver.  Add debug prints that help to
figure out the reason for bad packets and provide information when
debugging drivers.

Only generate a new xid at the start of getting a new lease.

"RFC 2131 4.1 Constructing and sending DHCP messages" has this:

| Selecting a new 'xid' for each retransmission is an implementation
| decision.  A client may choose to reuse the same 'xid' or select a new
| 'xid' for each retransmitted message.

We used to change xid for each request / response cycle but this ran
into problems with slow dhcp servers where we would change the xid too
frequently and would ignore late coming replies from the server.

Andre S points out that table 5 in "4.4.1 Initialization and
allocation of network address" says for the xid field in "DHCPREQUEST"
messages:

| 'xid' from server DHCPOFFER message

This seems to suggest that we need to use the same xid for the whole
DHCPDISCOVER / DHCPOFFER / DHCPREQUEST / DHCPACK exchange of messages.

Nothing else in the RFC is saying this though.

But since there are DHCP servers out there that depend on this, we
only generate a new xid when entering the INIT, REBOOTING and RENEWING
state.

I do wonder if we should just go with a static value of 0x04, which
was chosen by a fair dice roll, so guaranteed to be random.

Control startup of PROC_CERT and PROC_IKEV2.
Currenly PROC_PARENT sends the configuration to both PROC_CERT and

However, when PROC_IKEV2 receives IMSG_CTL_ACTIVE it does not know
the state of PROC_CERT: PROC_CERT might not have processed the
initial configuration while PROC_IKEV2 already sends requests to

is changed as follows:

(1) PROC_PARENT sends configuration to both PROC_CERT and PROC_IKEV2

Use `sb_mtx' instead of `inp_mtx' in receive path for inet sockets.

In soreceve(), we only touch `so_rcv' socket buffer, which has it's own
`sb_mtx' mutex(9) for protection. So, we can avoid solock() in this
path - it's enough to hold `sb_mtx' in soreceive() and around
corresponding sbappend*(). But not right now :)

This time we use shared netlock for some inet sockets in the soreceive()
path. To protect `so_rcv' buffer we use `inp_mtx' mutex(9) and the
pru_lock() to acquire this mutex(9) in socket layer. But the `inp_mtx'
mutex belongs to the PCB. We initialize socket before PCB, tcp(4)
sockets could exist without PCB, so use `sb_mtx' mutex(9) to protect
sockbuf stuff.

This diff mechanically replaces `inp_mtx' by `sb_mtx' in the receive
path. Only for sockets which already use `inp_mtx'. All other sockets
left as is. They will be converted later.

Since the `sb_mtx' is optional, the new SB_MTXLOCK flag introduced. If
this flag is set on `sb_flags', the `sb_mtx' mutex(9) should be taken.
New sb_mtx_lock() and sb_mtx_unlock() was introduced to hide this check.
They are temporary and will be replaced by mtx_enter() when all this
area will be converted to `sb_mtx' mutex(9).

Also, the new sbmtxassertlocked() function introduced to throw
corresponding assertion for SB_MTXLOCK marked buffers. This time only
sbappendaddr() calls it. This function is also temporary and will be
