Flags needinfo?(dcaratti)
Davide Caratti 2017-05-22 15:01:18 UTC Doc Text when ss reads TCP congestion window values from the kernel, it performs a cast from unsigned to signed 32-bit integer.

As a consequence, some values can overflow and be interpreted as a negative value: this is not correct, since the minimum congestion window value in the kernel is 0.

ss code was fixed to read/display cwnd as unsigned 32-bit integer. After the fix, no more negative cwnd values are observed in the output of 'ss'.

"ss" now displays correctly cwnd

Previously, the "ss" command displayed Transmission Control Protocol congestion window (TCP cwnd) values from the kernel, performing a cast from unsigned to signed 32-bit integer. As a consequence, some values can overflow and be interpreted as a negative value, since the minimum congestion window value in the kernel is `0`. With this update, the "ss" code has been fixed, and now no more negative cwnd values are observed.

As a consequence, some values can overflow and be interpreted as a negative value, since the minimum congestion window value in the kernel is `0`. With this update, the *ss* code has been fixed, and the utility no longer displays negative cwnd values.
