Andre Puschmann 2ca894df01 pdu: fortify RAR packing 
detected with ASAN trying to write negative number of padding bytes.

The patch checks the calculated length and returns with an error
if the length is negative.

Andre Puschmann d0d7ab4662 srsenb: log cell gain updates 
add a logline in info whenever the user updates the cell individual
gain. Note that this log happens before checking whether the
cell even exists and can be updated. This is mainly because
phy_common doesn't have an own logger object.

Andre Puschmann 3573644624 srsue: fix stdout metrics print when scells aren't configured yet 
during MAC reset, scells are reset to and their PCI is set to UINT32_MAX
which results in malformatted stdout prints, see below:

Random Access Transmission: seq=16, ra-rnti=0x2
Random Access Transmission: seq=14, ra-rnti=0x2
 0   4   -24    24  -1.1u   1.0   140  0.50    0.0     0%   0.0   0.0    0.0    0.0    67%

this patch checks the configured PCI value against UINT32_MAX and
prints "n/a" in case the scells aren't set yet.

Pedro Alvarez 0ad0e9acac Make sure that RLC entity is only re-created if it switches modes. 4 years ago
Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.
