tiny-printf: Handle NULL pointer argument to %s

2024-11-29T10:59:27+00:00

A NULL pointer argument to %s causes a NULL pointer dereference in the
fixed width numerical printout code, since p is overwritten with NULL.
In case of %s width is 0. Check width before dereferencing the pointer.

net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56+00:00

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as
well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due
to this code having an implicit dependency on do_tftpb().

Note that PXE is likely non-fonctional with NET_LWIP (or at least not
100% functional) because DHCP option 209 is not supported by the lwIP
library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled.

tiny-printf: Correct return values

2024-10-03T17:52:16+00:00

The sprintf() etc. functions are supposed to return the length of the
string written, but do not. Fix this by checking the amount of buffer
space used.

lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

tiny-printf: Handle %pM format when CONFIG_SPL_NET_SUPPORT is enabled

2021-08-21T22:23:02+00:00

%pM format string is used to print MAC-address and this is required while SPL
network boot.

This patch fixes the SPL boot issues like the following:

    Trying to boot from USB eth
    ## Error: flags type check failure for "ethaddr" <= "40309614M" (type: m)
    ## Error inserting "ethaddr" variable, errno=1
    eth0: eth_cpsw## Error: flags type check failure for "eth1addr" <=
    "81f01114M" (type: m)
    ## Error inserting "eth1addr" variable, errno=1
    , eth1: usb_ether
    eth_cpsw Waiting for PHY auto negotiation to complete......... TIMEOUT !
    Problem booting with BOOTP
    SPL: failed to boot from all boot devices

2020-05-01T15:03:24+00:00

The most basic printf("%i", value) formating string was missing,
add it for the sake of convenience.

tiny-printf: Support vsnprintf()

2019-10-31T11:22:53+00:00

Add a simple implementation of this function, to allow logging to be
enabled in the SPL or TPL for systems that rely on the tiny printf()
implementation.

To keep the code size small,

- The function is built only when logging is enabled, as it
  (currently) is not needed otherwise; and
- Like the existing implementation of snprintf(), its buffer-size
  parameter is ignored.

tiny-printf: Reorder code to support %p

2019-10-27T16:56:51+00:00

With a bit of code reordering we can support %p using the existing code
for ulong.

Move the %p code up and adjust the logic accordingly.
